 * #### Example:
 * This example creates an new class instance whose functions are prebound to the new'd object.
 * ```js
 * class Foo {

 * var logit = myFoo.log;
 * logit(); // logs [1, 2, 3] from the myFoo 'this' instance
 * ```
 *
 * #### Example:
 * This example creates a bound version of a service function, and copies it to another object
 * ```
 *
 * var SomeService = {
 *   this.data = [3, 4, 5];
 *   this.log = function() {

 * // and the second element is a function that returns a description of the input
 * let firstTuple = [ angular.isString, (input) => `Heres your string ${input}` ];

 * let secondTuple = [ angular.isNumber, (input) => `(${input}) That's a number!` ];
 *
 * let third = [ (input) => input === null,  (input) => `Oh, null...` ];
 *
 * let fourth = [ (input) => input === undefined,  (input) => `notdefined` ];

 * Matches state names using glob-like pattern strings.
 *
 * Globs can be used in specific APIs including:
 *
 * - [[StateService.is]]
 * - [[StateService.includes]]
 * - The first argument to Hook Registration functions like [[TransitionService.onStart]]
 *    - [[HookMatchCriteria]] and [[HookMatchCriterion]]
 *
 * A `Glob` string is a pattern which matches state names.
 * Nested state names are split into segments (separated by a dot) when processing.
 * The state named `foo.bar.baz` is split into three segments ['foo', 'bar', 'baz']
 *
 * Globs work according to the following rules:
 *
 * ### Exact match:
 *
 * The glob `'A.B'` matches the state named exactly `'A.B'`.
 *
 * | Glob        |Matches states named|Does not match state named|
 * |:------------|:--------------------|:---------------------|
 * | `'A'`       | `'A'`               | `'B'` , `'A.C'`      |
 * | `'A.B'`     | `'A.B'`             | `'A'` , `'A.B.C'`    |
 * | `'foo'`     | `'foo'`             | `'FOO'` , `'foo.bar'`|
 *
 * ### Single star (`*`)
 *
 * A single star (`*`) is a wildcard that matches exactly one segment.
 *
 * | Glob        |Matches states named  |Does not match state named |
 * |:------------|:---------------------|:--------------------------|
 * | `'*'`       | `'A'` , `'Z'`        | `'A.B'` , `'Z.Y.X'`       |
 * | `'A.*'`     | `'A.B'` , `'A.C'`    | `'A'` , `'A.B.C'`         |
 * | `'A.*.*'`   | `'A.B.C'` , `'A.X.Y'`| `'A'`, `'A.B'` , `'Z.Y.X'`|
 *
 * ### Double star (`**`)
 *
 * A double star (`'**'`) is a wildcard that matches *zero or more segments*
 *
 * | Glob        |Matches states named                           |Does not match state named         |
 * |:------------|:----------------------------------------------|:----------------------------------|
 * | `'**'`      | `'A'` , `'A.B'`, `'Z.Y.X'`                    | (matches all states)              |
 * | `'A.**'`    | `'A'` , `'A.B'` , `'A.C.X'`                   | `'Z.Y.X'`                         |
 * | `'**.X'`    | `'X'` , `'A.X'` , `'Z.Y.X'`                   | `'A'` , `'A.login.Z'`             |

     * This method is used to create a narrower context when injecting ancestor nodes.
     *
     * @example
     * `let ABCD = new ResolveContext([A, B, C, D]);`
     *
     * Given a path `[A, B, C, D]`, where `A`, `B`, `C` and `D` are nodes for states `a`, `b`, `c`, `d`:
     * When injecting `D`, `D` should have access to all resolvables from `A`, `B`, `C`, `D`.
     * However, `B` should only be able to access resolvables from `A`, `B`.
     *
     * When resolving for the `B` node, first take the full "To Path" Context `[A,B,C,D]` and limit to the subpath `[A,B]`.
     * `let AB = ABCD.subcontext(a)`

     * Creates a [[UIInjector]] Dependency Injector
     *
     * Returns a Dependency Injector for the Transition's target state (to state).
     * The injector provides resolve values which the target state has access to.
     *
     * The `UIInjector` can also provide values from the native root/global injector (ng1/ng2).
     *
     * #### Example:
     * ```js
     * .onEnter({ entering: 'myState' }, trans => {
     *   var myResolveValue = trans.injector().get('myResolve');
     *   // Inject a global service from the global/native injector (if it exists)
     *   var MyService = trans.injector().get('MyService');
     * })
     * ```
     *
     * In some cases (such as `onBefore`), you may need access to some resolve data but it has not yet been fetched.
     * You can use [[UIInjector.getAsync]] to get a promise for the data.
     * #### Example:
     * ```js
     * .onBefore({}, trans => {
     *   return trans.injector().getAsync('myResolve').then(myResolveValue =>
     *     return myResolveValue !== 'ABORT';
     *   });
     * });
     * ```
     *
     * If a `state` is provided, the injector that is returned will be limited to resolve values that the provided state has access to.
     * This can be useful if both a parent state `foo` and a child state `foo.bar` have both defined a resolve such as `data`.
     * #### Example:
     * ```js
     * .onEnter({ to: 'foo.bar' }, trans => {
     *   // returns result of `foo` state's `myResolve` resolve
     *   // even though `foo.bar` also has a `myResolve` resolve
     *   var fooData = trans.injector('foo').get('myResolve');
     * });
     * ```
     *
     * If you need resolve data from the exiting states, pass `'from'` as `pathName`.
     * The resolve data from the `from` path will be returned.
     * #### Example:
     * ```js
     * .onExit({ exiting: 'foo.bar' }, trans => {
     *   // Gets the resolve value of `myResolve` from the state being exited
     *   var fooData = trans.injector(null, 'from').get('myResolve');
     * });
     * ```
     *
     *
     * @param state Limits the resolves provided to only the resolves the provided state has access to.
     * @param pathName Default: `'to'`: Chooses the path for which to create the injector. Use this to access resolves for `exiting` states.
     *

/**
 * Matches URLs against patterns.
 *
 * Matches URLs against patterns and extracts named parameters from the path or the search
 * part of the URL.
 *
 * A URL pattern consists of a path pattern, optionally followed by '?' and a list of search (query)
 * parameters. Multiple search parameter names are separated by '&'. Search parameters
 * do not influence whether or not a URL is matched, but their values are passed through into
 * the matched parameters returned by [[UrlMatcher.exec]].
 *
 * - *Path parameters* are defined using curly brace placeholders (`/somepath/{param}`)
 * or colon placeholders (`/somePath/:param`).
 *
 * - *A parameter RegExp* may be defined for a param after a colon
 * (`/somePath/{param:[a-zA-Z0-9]+}`) in a curly brace placeholder.
 * The regexp must match for the url to be matched.
 * Should the regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
 *
 * Note: a RegExp parameter will encode its value using either [[ParamTypes.path]] or [[ParamTypes.query]].
 *
 * - *Custom parameter types* may also be specified after a colon (`/somePath/{param:int}`) in curly brace parameters.
 *   See [[UrlMatcherFactory.type]] for more information.
 *
 * - *Catch-all parameters* are defined using an asterisk placeholder (`/somepath/*catchallparam`).
 *   A catch-all * parameter value will contain the remainder of the URL.
 *
 * ---
 *
 * Parameter names may contain only word characters (latin letters, digits, and underscore) and
 * must be unique within the pattern (across both path and search parameters).
 * A path parameter matches any number of characters other than '/'. For catch-all
 * placeholders the path parameter matches any number of characters.
 *
 * Examples:
 *
 * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
 *   trailing slashes, and patterns have to match the entire path, not just a prefix.
 * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
 *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
 * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
 * * `'/user/{id:[^/]*}'` - Same as the previous example.
 * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
 *   parameter consists of 1 to 8 hex digits.
 * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
 *   path into the parameter 'path'.
 * * `'/files/*path'` - ditto.
 * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
 *   in the built-in  `date` ParamType matches `2014-11-12`) and provides a Date object in $stateParams.start

     * Given a ui-view and a ViewConfig, determines if they "match".

     * A ui-view has a fully qualified name (fqn) and a context object.  The fqn is built from its overall location in
     * the DOM, describing its nesting relationship to any parent ui-view tags it is nested inside of.
     *
     * A ViewConfig has a target ui-view name and a context anchor.  The ui-view name can be a simple name, or
     * can be a segmented ui-view path, describing a portion of a ui-view fqn.
     *
     * In order for a ui-view to match ViewConfig, ui-view's $type must match the ViewConfig's $type
     *
     * If the ViewConfig's target ui-view name is a simple name (no dots), then a ui-view matches if:
     * - the ui-view's name matches the ViewConfig's target name
     * - the ui-view's context matches the ViewConfig's anchor
     *
     * If the ViewConfig's target ui-view name is a segmented name (with dots), then a ui-view matches if:
     * - There exists a parent ui-view where:
     *    - the parent ui-view's name matches the first segment (index 0) of the ViewConfig's target name
     *    - the parent ui-view's context matches the ViewConfig's anchor
     * - And the remaining segments (index 1..n) of the ViewConfig's target name match the tail of the ui-view's fqn

     * Example:
     *
     * DOM:
     * <ui-view>                        <!-- created in the root context (name: "") -->
     *   <ui-view name="foo">                <!-- created in the context named: "A"      -->
     *     <ui-view>                    <!-- created in the context named: "A.B"    -->
     *       <ui-view name="bar">            <!-- created in the context named: "A.B.C"  -->
     *       </ui-view>
     *     </ui-view>
     *   </ui-view>
     * </ui-view>

     *  { fqn: "$default.foo.$default.bar", creationContext: { name: "A.B.C" } }
     * ]
     *
     * These four view configs all match the ui-view with the fqn: "$default.foo.$default.bar":
     *
     * - ViewConfig1: { uiViewName: "bar",                       uiViewContextAnchor: "A.B.C" }

     * - ViewConfig3: { uiViewName: "foo.$default.bar",          uiViewContextAnchor: "A" }
     * - ViewConfig4: { uiViewName: "$default.foo.$default.bar", uiViewContextAnchor: "" }
     *
     * Using ViewConfig3 as an example, it matches the ui-view with fqn "$default.foo.$default.bar" because:
     * - The ViewConfig's segmented target name is: [ "foo", "$default", "bar" ]
     * - There exists a parent ui-view (which has fqn: "$default.foo") where:
     *    - the parent ui-view's name "foo" matches the first segment "foo" of the ViewConfig's target name
     *    - the parent ui-view's context "A" matches the ViewConfig's anchor context "A"
     * - And the remaining segments [ "$default", "bar" ].join("."_ of the ViewConfig's target name match

     * #### Example:
     * Start app at `home` state.

     * This rule is matched when *no other rule* matches.

     *
     * The sort function should use these data, or data found on a specific type
     * of [[UrlRule]] (such as [[StateRule.state]]), to order the rules as desired.

     *
     * This method adds a UI-Router Plugin.
     * A plugin can enhance or change UI-Router behavior using any public API.
     *

     *
     * The plugin can then be published as a separate module.
     *

     * ```js
     * export class MyAuthPlugin implements UIRouterPlugin {

     *     this.name = "MyAuthPlugin";

     *
     *     let authCriteria = {
     *       to: (state) => state.data && state.data.requiresAuth

     *
     *     function authHook(transition: Transition) {
     *       let authService = transition.injector().get('AuthService');
     *       if (!authService.isAuthenticated()) {
     *         return $state.target('login');

     * Transition to a different state and/or parameters
     *
     * Convenience method for transitioning to a new state.
     *
     * `$state.go` calls `$state.transitionTo` internally but automatically sets options to
     * `{ location: true, inherit: true, relative: router.globals.$current, notify: true }`.
     * This allows you to use either an absolute or relative `to` argument (because of `relative: router.globals.$current`).
     * It also allows you to specify * only the parameters you'd like to update, while letting unspecified parameters
     * inherit from the current parameter values (because of `inherit: true`).
     *
     * #### Example:
     * ```js
     * let app = angular.module('app', ['ui.router']);
     *
     * app.controller('ctrl', function ($scope, $state) {

     * @param to Absolute state name, state object, or relative state path (relative to current state).
     *
     * Some examples:
     *
     * - `$state.go('contact.detail')` - will go to the `contact.detail` state
     * - `$state.go('^')` - will go to the parent state
     * - `$state.go('^.sibling')` - if current state is `home.child`, will go to the `home.sibling` state
     * - `$state.go('.child.grandchild')` - if current state is home, will go to the `home.child.grandchild` state
     *
     * @param params A map of the parameters that will be sent to the state, will populate $stateParams.
     *
     *    Any parameters that are not specified will be inherited from current parameter values (because of `inherit: true`).
     *    This allows, for example, going to a sibling state that shares parameters defined by a parent state.
     *
     * @param options Transition options
     *
     * @returns {promise} A promise representing the state of the new transition.

 * A basic angular1-like injector api

 *
 * UI-Router evolved from an angular 1 library to a framework agnostic library.
 * However, some of the `@uirouter/core` code uses these ng1 style APIs to support ng1 style dependency injection.
 *
 * This object provides a naive implementation of a globally scoped dependency injection system.
 * It supports the following DI approaches:
 *
 * ### Function parameter names
 *
 * A function's `.toString()` is called, and the parameter names are parsed.
 * This only works when the parameter names aren't "mangled" by a minifier such as UglifyJS.
 *
 * ```js
 * function injectedFunction(FooService, BarService) {
 *   // FooService and BarService are injected
 * }
 * ```
 *
 * ### Function annotation
 *
 * A function may be annotated with an array of dependency names as the `$inject` property.
 *
 * ```js
 * injectedFunction.$inject = [ 'FooService', 'BarService' ];
 * function injectedFunction(fs, bs) {
 *   // FooService and BarService are injected as fs and bs parameters
 * }
 * ```
 *
 * ### Array notation
 *
 * An array provides the names of the dependencies to inject (as strings).
 * The function is the last element of the array.
 *
 * ```js
 * [ 'FooService', 'BarService', function (fs, bs) {
 *   // FooService and BarService are injected as fs and bs parameters
 * }]
 * ```

     * `stateBuilder` object used internally by [[StateRegistry]].
     * This can be used to add custom functionality to ui-router,
     * for example inferring templateUrl based on the state name.
     *
     * When passing only a name, it returns the current (original or decorated) builder
     * function that matches `name`.
     *
     * The builder functions that can be decorated are listed below. Though not all
     * necessarily have a good use case for decoration, that is up to you to decide.
     *
     * In addition, users can attach custom decorators, which will generate new
     * properties within the state's internal definition. There is currently no clear
     * use-case for this beyond accessing internal states (i.e. $state.$current),
     * however, expect this to become increasingly relevant as we introduce additional
     * meta-programming features.
     *
     * **Warning**: Decorators should not be interdependent because the order of
     * execution of the builder functions in non-deterministic. Builder functions
     * should only be dependent on the state definition object and super function.
     *
     *
     * Existing builder functions and current return values:
     *
     * - **parent** `{object}` - returns the parent state object.
     * - **data** `{object}` - returns state data, including any inherited data that is not
     *   overridden by own values (if any).
     * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
     *   or `null`.
     * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is
     *   navigable).
     * - **params** `{object}` - returns an array of state params that are ensured to
     *   be a super-set of parent's params.
     * - **views** `{object}` - returns a views object where each key is an absolute view
     *   name (i.e. "viewName@stateName") and each value is the config object
     *   (template, controller) for the view. Even when you don't use the views object
     *   explicitly on a state config, one is still created for you internally.
     *   So by decorating this builder function you have access to decorating template
     *   and controller properties.
     * - **ownParams** `{object}` - returns an array of params that belong to the state,
     *   not including any params defined by ancestor states.
     * - **path** `{string}` - returns the full path from the root down to this state.
     *   Needed for state activation.
     * - **includes** `{object}` - returns an object that includes every state that
     *   would pass a `$state.includes()` test.
     *
     * #### Example:
     * Override the internal 'views' builder with a function that takes the state
     * definition, and a reference to the internal function being overridden:
     * ```js
     * $stateProvider.decorator('views', function (state, parent) {
     *   let result = {},
     *       views = parent(state);
     *
     *   angular.forEach(views, function (config, name) {
     *     let autoName = (state.name + '.' + name).replace('.', '/');
     *     config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
     *     result[name] = config;
     *   });
     *   return result;
     * });
     *
     * $stateProvider.state('home', {
     *   views: {
     *     'contact.list': { controller: 'ListController' },
     *     'contact.item': { controller: 'ItemController' }
     *   }
     * });
     * ```
     *
     *
     * ```js
     * // Auto-populates list and item views with /partials/home/contact/list.html,
     * // and /partials/home/contact/item.html, respectively.
     * $state.go('home');
     * ```
     *
     * @param {string} name The name of the builder function to decorate.
     * @param {object} func A function that is responsible for decorating the original
     * builder function. The function receives two parameters:
     *
     *   - `{object}` - state - The state config object.
     *   - `{object}` - super - The original builder function.
     *
     * @return {object} $stateProvider - $stateProvider instance

/**
 * `ui-sref`: A directive for linking to a state
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * ### Linked State
 * The attribute value of the `ui-sref` is the name of the state to link to.
 *
 * #### Example:
 * This will activate the `home` state when the link is clicked.
 * ```html
 * <a ui-sref="home">Home</a>
 * ```
 *
 * ### Relative Links
 * You can also use relative state paths within `ui-sref`, just like a relative path passed to `$state.go()` ([[StateService.go]]).
 * You just need to be aware that the path is relative to the state that *created* the link.
 * This allows a state to create a relative `ui-sref` which always targets the same destination.
 *
 * #### Example:
 * Both these links are relative to the parent state, even when a child state is currently active.
 * ```html
 * <a ui-sref=".child1">child 1 state</a>
 * <a ui-sref=".child2">child 2 state</a>
 * ```
 *
 * This link activates the parent state.
 * ```html
 * <a ui-sref="^">Return</a>
 * ```
 *
 * ### hrefs
 * If the linked state has a URL, the directive will automatically generate and
 * update the `href` attribute (using the [[StateService.href]]  method).
 *
 * #### Example:
 * Assuming the `users` state has a url of `/users/`
 * ```html
 * <a ui-sref="users" href="/users/">Users</a>
 * ```
 *
 * ### Parameter Values
 * In addition to the state name, a `ui-sref` can include parameter values which are applied when activating the state.
 * Param values can be provided in the `ui-sref` value after the state name, enclosed by parentheses.
 * The content inside the parentheses is an expression, evaluated to the parameter values.
 *
 * #### Example:
 * This example renders a list of links to users.
 * The state's `userId` parameter value comes from each user's `user.id` property.
 * ```html
 * <li ng-repeat="user in users">
 *   <a ui-sref="users.detail({ userId: user.id })">{{ user.displayName }}</a>
 * </li>
 * ```
 *
 * Note:
 * The parameter values expression is `$watch`ed for updates.
 *
 * ### Transition Options
 * You can specify [[TransitionOptions]] to pass to [[StateService.go]] by using the `ui-sref-opts` attribute.
 * Options are restricted to `location`, `inherit`, and `reload`.
 *
 * #### Example:
 * ```html
 * <a ui-sref="home" ui-sref-opts="{ reload: true }">Home</a>
 * ```
 *
 * ### Other DOM Events
 *
 * You can also customize which DOM events to respond to (instead of `click`) by
 * providing an `events` array in the `ui-sref-opts` attribute.
 *
 * #### Example:
 * ```html
 * <input type="text" ui-sref="contacts" ui-sref-opts="{ events: ['change', 'blur'] }">
 * ```
 *
 * ### Highlighting the active link
 * This directive can be used in conjunction with [[uiSrefActive]] to highlight the active link.
 *
 * ### Examples
 * If you have the following template:
 *
 * ```html
 * <a ui-sref="home">Home</a>
 * <a ui-sref="about">About</a>
 * <a ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
 *     </li>
 * </ul>
 * ```
 *
 * Then (assuming the current state is `contacts`) the rendered html including hrefs would be:
 *
 * ```html
 * <a href="#/home" ui-sref="home">Home</a>
 * <a href="#/about" ui-sref="about">About</a>
 * <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>
 *     </li>
 * </ul>
 *
 * <a href="#/home" ui-sref="home" ui-sref-opts="{reload: true}">Home</a>
 * ```
 *
 * ### Notes
 *
 * - You can use `ui-sref` to change **only the parameter values** by omitting the state name and parentheses.
 * #### Example:
 * Sets the `lang` parameter to `en` and remains on the same state.
 *
 * ```html
 * <a ui-sref="{ lang: 'en' }">English</a>
 * ```
 *
 * - A middle-click, right-click, or ctrl-click is handled (natively) by the browser to open the href in a new window, for example.
 *
 * - Unlike the parameter values expression, the state name is not `$watch`ed (for performance reasons).
 * If you need to dynamically update the state being linked to, use the fully dynamic [[uiState]] directive.

/**
 * `ui-state`: A fully dynamic directive for linking to a state
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * **This directive is very similar to [[uiSref]], but it `$observe`s and `$watch`es/evaluates all its inputs.**
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * ### Linked State
 * The attribute value of `ui-state` is an expression which is `$watch`ed and evaluated as the state to link to.
 * **This is in contrast with `ui-sref`, which takes a state name as a string literal.**
 *
 * #### Example:
 * Create a list of links.
 * ```html
 * <li ng-repeat="link in navlinks">
 *   <a ui-state="link.state">{{ link.displayName }}</a>
 * </li>
 * ```
 *
 * ### Relative Links
 * If the expression evaluates to a relative path, it is processed like [[uiSref]].
 * You just need to be aware that the path is relative to the state that *created* the link.
 * This allows a state to create relative `ui-state` which always targets the same destination.
 *
 * ### hrefs
 * If the linked state has a URL, the directive will automatically generate and
 * update the `href` attribute (using the [[StateService.href]]  method).
 *
 * ### Parameter Values
 * In addition to the state name expression, a `ui-state` can include parameter values which are applied when activating the state.
 * Param values should be provided using the `ui-state-params` attribute.
 * The `ui-state-params` attribute value is `$watch`ed and evaluated as an expression.
 *
 * #### Example:
 * This example renders a list of links with param values.
 * The state's `userId` parameter value comes from each user's `user.id` property.
 * ```html
 * <li ng-repeat="link in navlinks">
 *   <a ui-state="link.state" ui-state-params="link.params">{{ link.displayName }}</a>
 * </li>
 * ```
 *
 * ### Transition Options
 * You can specify [[TransitionOptions]] to pass to [[StateService.go]] by using the `ui-state-opts` attribute.
 * Options are restricted to `location`, `inherit`, and `reload`.
 * The value of the `ui-state-opts` is `$watch`ed and evaluated as an expression.
 *
 * #### Example:
 * ```html
 * <a ui-state="returnto.state" ui-state-opts="{ reload: true }">Home</a>
 * ```
 *
 * ### Other DOM Events
 *
 * You can also customize which DOM events to respond to (instead of `click`) by
 * providing an `events` array in the `ui-state-opts` attribute.
 *
 * #### Example:
 * ```html
 * <input type="text" ui-state="contacts" ui-state-opts="{ events: ['change', 'blur'] }">
 * ```
 *
 * ### Highlighting the active link
 * This directive can be used in conjunction with [[uiSrefActive]] to highlight the active link.
 *
 * ### Notes
 *
 * - You can use `ui-params` to change **only the parameter values** by omitting the state name and supplying only `ui-state-params`.
 *   However, it might be simpler to use [[uiSref]] parameter-only links.
 *
 * #### Example:
 * Sets the `lang` parameter to `en` and remains on the same state.
 *
 * ```html
 * <a ui-state="" ui-state-params="{ lang: 'en' }">English</a>
 * ```
 *
 * - A middle-click, right-click, or ctrl-click is handled (natively) by the browser to open the href in a new window, for example.

/**
 * `ui-sref-active` and `ui-sref-active-eq`: A directive that adds a CSS class when a `ui-sref` is active
 *
 * A directive working alongside [[uiSref]] and [[uiState]] to add classes to an element when the
 * related directive's state is active (and remove them when it is inactive).
 *
 * The primary use-case is to highlight the active link in navigation menus,
 * distinguishing it from the inactive menu items.
 *
 * ### Linking to a `ui-sref` or `ui-state`
 * `ui-sref-active` can live on the same element as `ui-sref`/`ui-state`, or it can be on a parent element.
 * If a `ui-sref-active` is a parent to more than one `ui-sref`/`ui-state`, it will apply the CSS class when **any of the links are active**.
 *
 * ### Matching
 *
 * The `ui-sref-active` directive applies the CSS class when the `ui-sref`/`ui-state`'s target state **or any child state is active**.
 * This is a "fuzzy match" which uses [[StateService.includes]].
 *
 * The `ui-sref-active-eq` directive applies the CSS class when the `ui-sref`/`ui-state`'s target state is directly active (not when child states are active).
 * This is an "exact match" which uses [[StateService.is]].
 *
 * ### Parameter values
 * If the `ui-sref`/`ui-state` includes parameter values, the current parameter values must match the link's values for the link to be highlighted.
 * This allows a list of links to the same state with different parameters to be rendered, and the correct one highlighted.
 *
 * #### Example:
 * ```html
 * <li ng-repeat="user in users" ui-sref-active="active">
 *   <a ui-sref="user.details({ userId: user.id })">{{ user.lastName }}</a>
 * </li>
 * ```
 *
 * ### Examples
 *
 * Given the following template:
 * #### Example:
 * ```html
 * <ul>
 *   <li ui-sref-active="active" class="item">
 *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
 *   </li>
 * </ul>
 * ```
 *
 * When the app state is `app.user` (or any child state),
 * and contains the state parameter "user" with value "bilbobaggins",
 * the resulting HTML will appear as (note the 'active' class):
 *
 * ```html
 * <ul>
 *   <li ui-sref-active="active" class="item active">
 *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
 *   </li>
 * </ul>
 * ```
 *
 * ### Glob mode
 *
 * It is possible to pass `ui-sref-active` an expression that evaluates to an object.
 * The objects keys represent active class names and values represent the respective state names/globs.
 * `ui-sref-active` will match if the current active state **includes** any of
 * the specified state names/globs, even the abstract ones.
 *
 * #### Example:
 * Given the following template, with "admin" being an abstract state:
 * ```html
 * <div ui-sref-active="{'active': 'admin.**'}">
 *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
 * </div>
 * ```
 *
 * Arrays are also supported as values in the `ngClass`-like interface.
 * This allows multiple states to add `active` class.
 *
 * #### Example:
 * Given the following template, with "admin.roles" being the current state, the class will be added too:
 * ```html
 * <div ui-sref-active="{'active': ['owner.**', 'admin.**']}">
 *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
 * </div>
 * ```
 *
 * When the current state is "admin.roles" the "active" class will be applied to both the `<div>` and `<a>` elements.
 * It is important to note that the state names/globs passed to `ui-sref-active` override any state provided by a linked `ui-sref`.
 *
 * ### Notes:
 *
 * - The class name is interpolated **once** during the directives link time (any further changes to the
 * interpolated value are ignored).
 *
 * - Multiple classes may be specified in a space-separated format: `ui-sref-active='class1 class2 class3'`

/**
 * `ui-view`: A viewport directive which is filled in by a view from the active state.
 *
 * ### Attributes
 *
 * - `name`: (Optional) A view name.
 *   The name should be unique amongst the other views in the same state.
 *   You can have views of the same name that live in different states.
 *   The ui-view can be targeted in a View using the name ([[Ng1StateDeclaration.views]]).
 *
 * - `autoscroll`: an expression. When it evaluates to true, the `ui-view` will be scrolled into view when it is activated.
 *   Uses [[$uiViewScroll]] to do the scrolling.
 *
 * - `onload`: Expression to evaluate whenever the view updates.
 *
 * #### Example:
 * A view can be unnamed or named.
 * ```html
 * <!-- Unnamed -->
 * <div ui-view></div>
 *
 * <!-- Named -->
 * <div ui-view="viewName"></div>
 *
 * <!-- Named (different style) -->
 * <ui-view name="viewName"></ui-view>
 * ```
 *
 * You can only have one unnamed view within any template (or root html). If you are only using a
 * single view and it is unnamed then you can populate it like so:
 *
 * ```html
 * <div ui-view></div>
 * $stateProvider.state("home", {
 *   template: "<h1>HELLO!</h1>"
 * })
 * ```
 *
 * The above is a convenient shortcut equivalent to specifying your view explicitly with the
 * [[Ng1StateDeclaration.views]] config property, by name, in this case an empty name:
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }
 * })
 * ```
 *
 * But typically you'll only use the views property if you name your view or have more than one view
 * in the same template. There's not really a compelling reason to name a view if its the only one,
 * but you could if you wanted, like so:
 *
 * ```html
 * <div ui-view="main"></div>
 * ```
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "main": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }
 * })
 * ```
 *
 * Really though, you'll use views to set up multiple views:
 *
 * ```html
 * <div ui-view></div>
 * <div ui-view="chart"></div>
 * <div ui-view="data"></div>
 * ```
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     },
 *     "chart": {
 *       template: "<chart_thing/>"
 *     },
 *     "data": {
 *       template: "<data_thing/>"
 *     }
 *   }
 * })
 * ```
 *
 * #### Examples for `autoscroll`:
 * ```html
 * <!-- If autoscroll present with no expression,
 *      then scroll ui-view into view -->
 * <ui-view autoscroll/>
 *
 * <!-- If autoscroll present with valid expression,
 *      then scroll ui-view into view if expression evaluates to true -->
 * <ui-view autoscroll='true'/>
 * <ui-view autoscroll='false'/>
 * <ui-view autoscroll='scopeVariable'/>
 * ```
 *
 * Resolve data:
 *
 * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
 * can be customized using [[Ng1ViewDeclaration.resolveAs]]).  This can be then accessed from the template.
 *
 * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
 * controller is instantiated.  The `$onInit()` hook can be used to perform initialization code which
 * depends on `$resolve` data.
 *
 * #### Example:
 * ```js
 * $stateProvider.state('home', {
 *   template: '<my-component user="$resolve.user"></my-component>',
 *   resolve: {
 *     user: function(UserService) { return UserService.fetchUser(); }
 *   }
 * });
 * ```

 * Configure several aspects of error handling in AngularJS if used as a setter or return the
 * current configuration if used as a getter. The following options are supported:
 *
 * - **objectMaxDepth**: The maximum depth to which objects are traversed when stringified for error messages.
 *
 * Omitted or undefined options will leave the corresponding configuration values unchanged.
 *
 * @param {Object=} config - The configuration object. May only contain the options that need to be
 *     updated. Supported keys:
 *
 * * `objectMaxDepth`  **{Number}** - The max depth for stringifying objects. Setting to a
 *   non-positive or non-numeric value, removes the max depth limit.
 *   Default: 5
 *
 * * `urlErrorParamsEnabled`  **{Boolean}** - Specifies wether the generated error url will
 *   contain the parameters of the thrown error. Disabling the parameters can be useful if the
 *   generated error url is very long.
 *
 *   Default: true. When used without argument, it returns the current value.

 * This object provides a utility for producing rich Error messages within
 * AngularJS. It can be called as follows:
 *
 * var exampleMinErr = minErr('example');
 * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
 *
 * The above creates an instance of minErr in the example namespace. The
 * resulting error will have a namespaced error code of example.one.  The
 * resulting error will replace {0} with the value of foo, and {1} with the
 * value of bar. The object is not restricted in the number of arguments it can
 * take.
 *
 * If fewer arguments are specified than necessary for interpolation, the extra
 * interpolation markers will be preserved in the final string.
 *
 * Since data will be parsed statically during a build step, some restrictions
 * are applied with respect to how minErr instances are created and called.
 * Instances should have names of the form namespaceMinErr for a minErr created
 * using minErr('namespace') . Error codes, namespaces and template strings
 * should all be static strings, not variables or general expressions.
 *
 * @param {string} module The namespace to use for the new minErr instance.
 * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
 *   error from returned function, for cases when a particular type of error is useful.
 * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

 * @ngdoc function

 * @description
 * Creates a deep copy of `source`, which should be an object or an array. This functions is used
 * internally, mostly in the change-detection code. It is not intended as an all-purpose copy
 * function, and has several limitations (see below).
 *
 * * If no destination is supplied, a copy of the object or array is created.
 * * If a destination is provided, all of its elements (for arrays) or properties (for objects)
 *   are deleted and then all elements/properties from the source are copied to it.
 * * If `source` is not an object or array (inc. `null` and `undefined`), `source` is returned.
 * * If `source` is identical to `destination` an exception will be thrown.
 *
 * <br />
 *
 * <div class="alert alert-warning">
 *   Only enumerable properties are taken into account. Non-enumerable properties (both on `source`
 *   and on `destination`) will be ignored.
 * </div>
 *
 * <div class="alert alert-warning">
 *   `angular.copy` does not check if destination and source are of the same type. It's the
 *   developer's responsibility to make sure they are compatible.

/**
 * @ngdoc directive
 * @name ngApp
 * @module ng
 *
 * @element ANY
 * @param {angular.Module} ngApp an optional application
 *   {@link angular.module module} name to load.
 * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
 *   created in "strict-di" mode. This means that the application will fail to invoke functions which
 *   do not use explicit function annotation (and are thus unsuitable for minification), as described
 *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
 *   tracking down the root of these bugs.
 *
 * @description
 *
 * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
 * designates the **root element** of the application and is typically placed near the root element
 * of the page - e.g. on the `<body>` or `<html>` tags.
 *
 * There are a few things to keep in mind when using `ngApp`:
 * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
 *   found in the document will be used to define the root element to auto-bootstrap as an
 *   application. To run multiple applications in an HTML document you must manually bootstrap them using
 *   {@link angular.bootstrap} instead.
 * - AngularJS applications cannot be nested within each other.
 * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
 *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
 *   {@link ngRoute.ngView `ngView`}.
 *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
 *   causing animations to stop working and making the injector inaccessible from outside the app.
 *
 * You can specify an **AngularJS module** to be used as the root module for the application.  This
 * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
 * should contain the application code needed or have dependencies on other modules that will
 * contain the code. See {@link angular.module} for more information.
 *
 * In the example below if the `ngApp` directive were not placed on the `html` element then the
 * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
 * would not be resolved to `3`.
 *
 * @example
 *
 * ### Simple Usage
 *
 * `ngApp` is the easiest, and most common way to bootstrap an application.
 *
 <example module="ngAppDemo" name="ng-app">
   <file name="index.html">
   <div ng-controller="ngAppDemoController">
     I can add: {{a}} + {{b}} =  {{ a+b }}
   </div>
   </file>
   <file name="script.js">
   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
     $scope.a = 1;
     $scope.b = 2;
   });
   </file>
 </example>
 *
 * @example
 *
 * ### With `ngStrictDi`
 *
 * Using `ngStrictDi`, you would see something like this:
 *
 <example ng-app-included="true" name="strict-di">
   <file name="index.html">
   <div ng-app="ngAppStrictDemo" ng-strict-di>
       <div ng-controller="GoodController1">
           I can add: {{a}} + {{b}} =  {{ a+b }}

           <p>This renders because the controller does not fail to
              instantiate, by using explicit annotation style (see
              script.js for details)
           </p>
       </div>

       <div ng-controller="GoodController2">
           Name: <input ng-model="name"><br />
           Hello, {{name}}!

           <p>This renders because the controller does not fail to
              instantiate, by using explicit annotation style
              (see script.js for details)
           </p>
       </div>

       <div ng-controller="BadController">
           I can add: {{a}} + {{b}} =  {{ a+b }}

           <p>The controller could not be instantiated, due to relying
              on automatic function annotations (which are disabled in
              strict mode). As such, the content of this section is not
              interpolated, and there should be an error in your web console.

     * @description
     *
     * The `angular.module` is a global place for creating, registering and retrieving AngularJS
     * modules.
     * All modules (AngularJS core or 3rd party) that should be available to an application must be
     * registered using this mechanism.
     *
     * Passing one argument retrieves an existing {@link angular.Module},
     * whereas passing more than one argument creates a new {@link angular.Module}
     *
     *
     * # Module
     *
     * A module is a collection of services, directives, controllers, filters, and configuration information.
     * `angular.module` is used to configure the {@link auto.$injector $injector}.
     *
     * ```js
     * // Create a new module
     * var myModule = angular.module('myModule', []);
     *
     * // register a new service
     * myModule.value('appName', 'MyCoolApp');
     *
     * // configure existing services inside initialization blocks.
     * myModule.config(['$locationProvider', function($locationProvider) {
     *   // Configure existing providers
     *   $locationProvider.hashPrefix('!');
     * }]);
     * ```
     *
     * Then you can create an injector and load your modules like this:
     *
     * ```js
     * var injector = angular.injector(['ng', 'myModule'])
     * ```
     *
     * However it's more likely that you'll just use
     * {@link ng.directive:ngApp ngApp} or
     * {@link angular.bootstrap} to simplify this process for you.
     *
     * @param {!string} name The name of the module to create or retrieve.
     * @param {!Array.<string>=} requires If specified then new module is being created. If
     *        unspecified then the module is being retrieved for further configuration.
     * @param {Function=} configFn Optional configuration function for the module. Same as
     *        {@link angular.Module#config Module#config()}.
     * @returns {angular.Module} new module with the {@link angular.Module} api.

/**
 * @ngdoc function
 * @name angular.element
 * @module ng
 * @kind function
 *
 * @description
 * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
 *
 * If jQuery is available, `angular.element` is an alias for the
 * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
 * delegates to AngularJS's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
 *
 * jqLite is a tiny, API-compatible subset of jQuery that allows
 * AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
 * commonly needed functionality with the goal of having a very small footprint.
 *
 * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
 * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
 * specific version of jQuery if multiple versions exist on the page.
 *
 * <div class="alert alert-info">**Note:** All element references in AngularJS are always wrapped with jQuery or
 * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
 *
 * <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
 * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
 * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
 *
 * ## AngularJS's jqLite
 * jqLite provides only the following jQuery methods:
 *
 * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
 * - [`after()`](http://api.jquery.com/after/)
 * - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements
 *   so will not work correctly when invoked on a jqLite object containing more than one DOM node
 * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
 * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
 * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
 * - [`clone()`](http://api.jquery.com/clone/)
 * - [`contents()`](http://api.jquery.com/contents/)
 * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
 *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
 * - [`data()`](http://api.jquery.com/data/)
 * - [`detach()`](http://api.jquery.com/detach/)
 * - [`empty()`](http://api.jquery.com/empty/)
 * - [`eq()`](http://api.jquery.com/eq/)
 * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
 * - [`hasClass()`](http://api.jquery.com/hasClass/)
 * - [`html()`](http://api.jquery.com/html/)
 * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
 * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
 * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
 * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
 * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
 * - [`prepend()`](http://api.jquery.com/prepend/)
 * - [`prop()`](http://api.jquery.com/prop/)
 * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
 * - [`remove()`](http://api.jquery.com/remove/)
 * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
 * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
 * - [`removeData()`](http://api.jquery.com/removeData/)
 * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
 * - [`text()`](http://api.jquery.com/text/)
 * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
 * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
 * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
 * - [`val()`](http://api.jquery.com/val/)
 * - [`wrap()`](http://api.jquery.com/wrap/)
 *
 * ## jQuery/jqLite Extras
 * AngularJS also provides the following additional methods and events to both jQuery and jqLite:
 *
 * ### Events
 * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
 *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
 *    element before it is removed.
 *
 * ### Methods
 * - `controller(name)` - retrieves the controller of the current element or its parent. By default
 *   retrieves controller associated with the `ngController` directive. If `name` is provided as
 *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
 *   `'ngModel'`).
 * - `injector()` - retrieves the injector of the current element or its parent.
 * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
 *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
 *   be enabled.
 * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
 *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
 *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
 *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
 * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
 *   parent element is reached.
 *
 * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
 * https://github.com/angular/angular.js/issues/14251 for more information.
 *
 * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
 * @returns {Object} jQuery object.

 * @kind function
 *
 * @description
 * Creates an injector object that can be used for retrieving services as well as for
 * dependency injection (see {@link guide/di dependency injection}).
 *
 * @param {Array.<string|Function>} modules A list of module functions or their aliases. See
 *     {@link angular.module}. The `ng` module must be explicitly added.
 * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
 *     disallows argument name annotation inference.
 * @returns {injector} Injector object. See {@link auto.$injector $injector}.
 *
 * @example
 * Typical usage
 * ```js
 *   // create an injector
 *   var $injector = angular.injector(['ng']);
 *
 *   // use the injector to kick off your application
 *   // use the type inference to auto inject arguments, or use implicit injection
 *   $injector.invoke(function($rootScope, $compile, $document) {
 *     $compile($document)($rootScope);
 *     $rootScope.$digest();
 *   });
 * ```
 *
 * Sometimes you want to get access to the injector of a currently running AngularJS app
 * from outside AngularJS. Perhaps, you want to inject and compile some markup after the
 * application has been bootstrapped. You can do this using the extra `injector()` added
 * to JQuery/jqLite elements. See {@link angular.element}.
 *
 * *This is fairly rare but could be the case if a third party library is injecting the
 * markup.*
 *
 * In the following example a new block of HTML containing a `ng-controller`
 * directive is added to the end of the document body by JQuery. We then compile and link
 * it into the current AngularJS scope.
 *
 * ```js
 * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
 * $(document.body).append($div);
 *
 * angular.element(document).injector().invoke(function($compile) {
 *   var scope = angular.element($div).scope();
 *   $compile($div)(scope);

/**
 * @ngdoc service
 * @name $injector
 *
 * @description
 *
 * `$injector` is used to retrieve object instances as defined by
 * {@link auto.$provide provider}, instantiate types, invoke methods,
 * and load modules.
 *
 * The following always holds true:
 *
 * ```js
 *   var $injector = angular.injector();
 *   expect($injector.get('$injector')).toBe($injector);
 *   expect($injector.invoke(function($injector) {
 *     return $injector;
 *   })).toBe($injector);
 * ```
 *
 * ## Injection Function Annotation
 *
 * JavaScript does not have annotations, and annotations are needed for dependency injection. The
 * following are all valid ways of annotating function with injection arguments and are equivalent.
 *
 * ```js
 *   // inferred (only works if code not minified/obfuscated)
 *   $injector.invoke(function(serviceA){});
 *
 *   // annotated
 *   function explicit(serviceA) {};
 *   explicit.$inject = ['serviceA'];
 *   $injector.invoke(explicit);
 *
 *   // inline
 *   $injector.invoke(['serviceA', function(serviceA){}]);
 * ```
 *
 * ### Inference
 *
 * In JavaScript calling `toString()` on a function returns the function definition. The definition
 * can then be parsed and the function arguments can be extracted. This method of discovering
 * annotations is disallowed when the injector is in strict mode.
 * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
 * argument names.
 *
 * ### `$inject` Annotation
 * By adding an `$inject` property onto a function the injection parameters can be specified.
 *
 * ### Inline
 * As an array of injection names, where the last item in the array is the function to call.

/**
 * @ngdoc method
 * @name $injector#annotate
 *
 * @description
 * Returns an array of service names which the function is requesting for injection. This API is
 * used by the injector to determine which services need to be injected into the function when the
 * function is invoked. There are three ways in which the function can be annotated with the needed
 * dependencies.
 *
 * #### Argument names
 *
 * The simplest form is to extract the dependencies from the arguments of the function. This is done
 * by converting the function into a string using `toString()` method and extracting the argument
 * names.
 * ```js
 *   // Given
 *   function MyController($scope, $route) {
 *     // ...
 *   }
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * ```
 *
 * You can disallow this method by using strict injection mode.
 *
 * This method does not work with code minification / obfuscation. For this reason the following
 * annotation strategies are supported.
 *
 * #### The `$inject` property
 *
 * If a function has an `$inject` property and its value is an array of strings, then the strings
 * represent names of services to be injected into the function.
 * ```js
 *   // Given
 *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
 *     // ...
 *   }
 *   // Define function dependencies
 *   MyController['$inject'] = ['$scope', '$route'];
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * ```
 *
 * #### The array notation
 *
 * It is often desirable to inline Injected functions and that's when setting the `$inject` property
 * is very inconvenient. In these situations using the array notation to specify the dependencies in
 * a way that survives minification is a better choice:
 *
 * ```js
 *   // We wish to write this (not minification / obfuscation safe)
 *   injector.invoke(function($compile, $rootScope) {
 *     // ...
 *   });
 *
 *   // We are forced to write break inlining
 *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
 *     // ...
 *   };
 *   tmpFn.$inject = ['$compile', '$rootScope'];
 *   injector.invoke(tmpFn);
 *
 *   // To better support inline function the inline annotation is supported
 *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
 *     // ...
 *   }]);
 *
 *   // Therefore
 *   expect(injector.annotate(
 *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
 *    ).toEqual(['$compile', '$rootScope']);
 * ```
 *
 * @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
 * be retrieved as described above.
 *
 * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
 *
 * @returns {Array.<string>} The names of the services which the function requires.

 * Add the specified modules to the current injector.
 *
 * This method will add each of the injectables to the injector and execute all of the config and run

 * * Modules cannot be unloaded.
 *
 * You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded
 * into the injector, which may indicate whether the script has been executed already.

/**
 * @ngdoc service

 *
 * @description
 *
 * The {@link auto.$provide $provide} service has a number of methods for registering components
 * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
 * {@link angular.Module}.
 *
 * An AngularJS **service** is a singleton object created by a **service factory**.  These **service
 * factories** are functions which, in turn, are created by a **service provider**.
 * The **service providers** are constructor functions. When instantiated they must contain a
 * property called `$get`, which holds the **service factory** function.
 *
 * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
 * correct **service provider**, instantiating it and then calling its `$get` **service factory**
 * function to get the instance of the **service**.
 *
 * Often services have no configuration options and there is no need to add methods to the service
 * provider.  The provider will be no more than a constructor function with a `$get` property. For
 * these cases the {@link auto.$provide $provide} service has additional helper methods to register
 * services without specifying a provider.
 *
 * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
 *     {@link auto.$injector $injector}
 * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
 *     providers and services.
 * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
 *     services, not providers.
 * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
 *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
 *     given factory function.
 * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
 *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
 *      a new object using the given constructor function.
 * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that
 *      will be able to modify or replace the implementation of another service.

 */

/**
 * @ngdoc method
 * @name $provide#provider
 * @description
 *
 * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
 * are constructor functions, whose instances are responsible for "providing" a factory for a
 * service.
 *
 * Service provider names start with the name of the service they provide followed by `Provider`.
 * For example, the {@link ng.$log $log} service has a provider called
 * {@link ng.$logProvider $logProvider}.
 *
 * Service provider objects can have additional methods which allow configuration of the provider
 * and its service. Importantly, you can configure what kind of service is created by the `$get`
 * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
 * method {@link ng.$logProvider#debugEnabled debugEnabled}
 * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
 * console or not.
 *
 * It is possible to inject other providers into the provider function,
 * but the injected provider must have been defined before the one that requires it.
 *
 * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
                        'Provider'` key.
 * @param {(Object|function())} provider If the provider is:
 *
 *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
 *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
 *   - `Constructor`: a new instance of the provider will be created using
 *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
 *
 * @returns {Object} registered provider instance

 * @example
 *
 * The following example shows how to create a simple event tracking service and register it using
 * {@link auto.$provide#provider $provide.provider()}.
 *
 * ```js
 *  // Define the eventTracker provider
 *  function EventTrackerProvider() {
 *    var trackingUrl = '/track';

   * @description
   * When called, it scrolls to the element related to the specified `hash` or (if omitted) to the
   * current value of {@link ng.$location#hash $location.hash()}, according to the rules specified
   * in the
   * [HTML5 spec](http://www.w3.org/html/wg/drafts/html/master/browsers.html#an-indicated-part-of-the-document).
   *
   * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
   * match any anchor whenever it changes. This can be disabled by calling
   * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
   *
   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
   * vertical scroll-offset (either fixed or dynamic).
   *
   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
   *                       {@link ng.$location#hash $location.hash()} will be used.
   *
   * @property {(number|function|jqLite)} yOffset
   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
   * positioned elements at the top of the page, such as navbars, headers etc.
   *
   * `yOffset` can be specified in various ways:
   * - **number**: A fixed number of pixels to be used as offset.<br /><br />
   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
   *   a number representing the offset (in pixels).<br /><br />
   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
   *   the top of the page to the element's bottom will be used as offset.<br />
   *   **Note**: The element will be taken into account only as long as its `position` is set to
   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
   *   their height and/or positioning according to the viewport's size.
   *
   * <br />
   * <div class="alert alert-warning">
   * In order for `yOffset` to work properly, scrolling should take place on the document's root and
   * not some child element.

 *
 * The compilation is a process of walking the DOM tree and matching DOM elements to

 *
 * <div class="alert alert-warning">
 * **Note:** This document is an in-depth reference of all directive options.
 * For a gentle introduction to directives with examples of common use cases,
 * see the {@link guide/directive directive guide}.
 * </div>
 *
 * ## Comprehensive Directive API
 *
 * There are many different options for a directive.
 *
 * The difference resides in the return value of the factory function.
 * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
 * that defines the directive properties, or just the `postLink` function (all other properties will have
 * the default values).
 *
 * <div class="alert alert-success">
 * **Best Practice:** It's recommended to use the "directive definition object" form.
 * </div>
 *
 * Here's an example directive declared with a Directive Definition Object:
 *
 * ```js
 *   var myModule = angular.module(...);
 *
 *   myModule.directive('directiveName', function factory(injectables) {
 *     var directiveDefinitionObject = {
 *       {@link $compile#-priority- priority}: 0,
 *       {@link $compile#-template- template}: '<div></div>', // or // function(tElement, tAttrs) { ... },
 *       // or
 *       // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
 *       {@link $compile#-transclude- transclude}: false,
 *       {@link $compile#-restrict- restrict}: 'A',
 *       {@link $compile#-templatenamespace- templateNamespace}: 'html',
 *       {@link $compile#-scope- scope}: false,
 *       {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
 *       {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
 *       {@link $compile#-bindtocontroller- bindToController}: false,
 *       {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
 *       {@link $compile#-multielement- multiElement}: false,
 *       {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
 *         return {
 *            {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
 *            {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
 *         }
 *         // or
 *         // return function postLink( ... ) { ... }
 *       },
 *       // or
 *       // {@link $compile#-link- link}: {
 *       //  {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
 *       //  {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
 *       // }
 *       // or
 *       // {@link $compile#-link- link}: function postLink( ... ) { ... }
 *     };
 *     return directiveDefinitionObject;
 *   });
 * ```
 *
 * <div class="alert alert-warning">
 * **Note:** Any unspecified options will use the default value. You can see the default values below.
 * </div>
 *
 * Therefore the above can be simplified as:
 *
 * ```js
 *   var myModule = angular.module(...);
 *
 *   myModule.directive('directiveName', function factory(injectables) {
 *     var directiveDefinitionObject = {
 *       link: function postLink(scope, iElement, iAttrs) { ... }
 *     };
 *     return directiveDefinitionObject;
 *     // or
 *     // return function postLink(scope, iElement, iAttrs) { ... }
 *   });
 * ```
 *
 * ### Life-cycle hooks
 * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the
 * directive:
 * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
 *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on
 *   this element). This is a good place to put initialization code for your controller.
 * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
 *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
 *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
 *   component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
 *   also be called when your bindings are initialized.
 * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
 *   changes. Any actions that you wish to take in response to the changes that you detect must be
 *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
 *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
 *   be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
 *   if detecting changes, you must store the previous value(s) for comparison to the current values.
 * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
 *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
 *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
 *   components will have their `$onDestroy()` hook called before child components.
 * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
 *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
 *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
 *   they are waiting for their template to load asynchronously and their own compilation and linking has been
 *   suspended until that occurs.
 *
 * #### Comparison with life-cycle hooks in the new Angular
 * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are
 * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:
 *
 * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.
 * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.
 *   In Angular you can only define hooks on the prototype of the Component class.
 * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to
 *   `ngDoCheck` in Angular.
 * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
 *   propagated throughout the application.
 *   Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
 *   error or do nothing depending upon the state of `enableProdMode()`.
 *
 * #### Life-cycle hook examples
 *
 * This example shows how you can check for mutations to a Date object even though the identity of the object
 * has not changed.
 *
 * <example name="doCheckDateExample" module="do-check-module">
 *   <file name="app.js">
 *     angular.module('do-check-module', [])
 *       .component('app', {
 *         template:
 *           'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
 *           'Date: {{ $ctrl.date }}' +
 *           '<test date="$ctrl.date"></test>',
 *         controller: function() {
 *           this.date = new Date();
 *           this.month = this.date.getMonth();
 *           this.updateDate = function() {
 *             this.date.setMonth(this.month);
 *           };
 *         }
 *       })
 *       .component('test', {
 *         bindings: { date: '<' },
 *         template:
 *           '<pre>{{ $ctrl.log | json }}</pre>',
 *         controller: function() {
 *           var previousValue;
 *           this.log = [];
 *           this.$doCheck = function() {
 *             var currentValue = this.date && this.date.valueOf();
 *             if (previousValue !== currentValue) {
 *               this.log.push('doCheck: date mutated: ' + this.date);
 *               previousValue = currentValue;
 *             }
 *           };
 *         }
 *       });
 *   </file>
 *   <file name="index.html">
 *     <app></app>
 *   </file>
 * </example>
 *
 * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
 * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
 * arrays or objects can have a negative impact on your application performance)
 *
 * <example name="doCheckArrayExample" module="do-check-module">
 *   <file name="index.html">
 *     <div ng-init="items = []">
 *       <button ng-click="items.push(items.length)">Add Item</button>
 *       <button ng-click="items = []">Reset Items</button>
 *       <pre>{{ items }}</pre>
 *       <test items="items"></test>
 *     </div>
 *   </file>
 *   <file name="app.js">
 *      angular.module('do-check-module', [])
 *        .component('test', {
 *          bindings: { items: '<' },
 *          template:
 *            '<pre>{{ $ctrl.log | json }}</pre>',
 *          controller: function() {
 *            this.log = [];
 *
 *            this.$doCheck = function() {
 *              if (this.items_ref !== this.items) {
 *                this.log.push('doCheck: items changed');
 *                this.items_ref = this.items;
 *              }
 *              if (!angular.equals(this.items_clone, this.items)) {
 *                this.log.push('doCheck: items mutated');
 *                this.items_clone = angular.copy(this.items);
 *              }
 *            };
 *          }
 *        });
 *   </file>
 * </example>

 *
 * ### Directive Definition Object
 *
 * The directive definition object provides instructions to the {@link ng.$compile
 * compiler}. The attributes are:
 *
 * #### `multiElement`
 * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
 * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
 * together as the directive elements. It is recommended that this feature be used on directives
 * which are not strictly behavioral (such as {@link ngClick}), and which
 * do not manipulate or replace child nodes (such as {@link ngInclude}).
 *
 * #### `priority`
 * When there are multiple directives defined on a single DOM element, sometimes it
 * is necessary to specify the order in which the directives are applied. The `priority` is used
 * to sort the directives before their `compile` functions get called. Priority is defined as a
 * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
 * are also run in priority order, but post-link functions are run in reverse order. The order
 * of directives with the same priority is undefined. The default priority is `0`.
 *
 * #### `terminal`
 * If set to true then the current `priority` will be the last set of directives
 * which will execute (any directives at the current priority will still execute
 * as the order of execution on same `priority` is undefined). Note that expressions
 * and other directives used in the directive's template will also be excluded from execution.
 *
 * #### `scope`
 * The scope property can be `false`, `true`, or an object:
 *
 * * **`false` (default):** No scope will be created for the directive. The directive will use its
 * parent's scope.
 *
 * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
 * the directive's element. If multiple directives on the same element request a new scope,
 * only one new scope is created.
 *
 * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
 * The 'isolate' scope differs from normal scope in that it does not prototypically
 * inherit from its parent scope. This is useful when creating reusable components, which should not
 * accidentally read or modify data in the parent scope. Note that an isolate scope
 * directive without a `template` or `templateUrl` will not apply the isolate scope
 * to its children elements.
 *
 * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
 * directive's element. These local properties are useful for aliasing values for templates. The keys in
 * the object hash map to the name of the property on the isolate scope; the values define how the property
 * is bound to the parent scope, via matching attributes on the directive's element:
 *
 * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
 *   always a string since DOM attributes are strings. If no `attr` name is specified then the
 *   attribute name is assumed to be the same as the local name. Given `<my-component
 *   my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
 *   the directive's scope property `localName` will reflect the interpolated value of `hello
 *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
 *   scope. The `name` is read from the parent scope (not the directive's scope).
 *
 * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
 *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
 *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
 *   name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
 *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
 *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
 *   `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute
 *   isn't  optional and doesn't exist, an exception
 *   ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes
 *   to the local value, since it will be impossible to sync them back to the parent scope.
 *
 *   By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
 *   method is used for tracking changes, and the equality check is based on object identity.
 *   However, if an object literal or an array literal is passed as the binding expression, the
 *   equality check is done by value (using the {@link angular.equals} function). It's also possible
 *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
 *   `$watchCollection`}: use `=*` or `=*attr`
 *
  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
 *   expression passed via the attribute `attr`. The expression is evaluated in the context of the
 *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
 *   local name.
 *
 *   For example, given `<my-component my-attr="parentModel">` and directive definition of
 *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
 *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
 *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
 *   two caveats:
 *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply
 *     sets the same value. That means if your bound value is an object, changes to its properties
 *     in the isolated scope will be reflected in the parent scope (because both reference the same object).
 *     2. one-way binding watches changes to the **identity** of the parent value. That means the
 *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
 *     to the value has changed. In most cases, this should not be of concern, but can be important
 *     to know if you one-way bind to an object, and then replace that object in the isolated scope.
 *     If you now change a property of the object in your parent scope, the change will not be
 *     propagated to the isolated scope, because the identity of the object on the parent scope
 *     has not changed. Instead you must assign a new object.
 *
 *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
 *   back to the parent. However, it does not make this completely impossible.
 *
 *   By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
 *   method is used for tracking changes, and the equality check is based on object identity.
 *   It's also possible to watch the evaluated value shallowly with
 *   {@link ng.$rootScope.Scope#$watchCollection `$watchCollection`}: use `<*` or `<*attr`
 *
 * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
 *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.
 *   Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
 *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
 *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
 *   via an expression to the parent scope. This can be done by passing a map of local variable names
 *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
 *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
 *
 * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.
 * The marker must come after the mode and before the attribute name.
 * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.
 * This is useful to refine the interface directives provide.
 * One subtle difference between optional and non-optional happens **when the binding attribute is not
 * set**:
 * - the binding is optional: the property will not be defined
 * - the binding is not optional: the property is defined
 *
 * ```js
 *app.directive('testDir', function() {
    return {
      scope: {
        notoptional: '=',
        optional: '=?',
      },
      bindToController: true,
      controller: function() {
        this.$onInit = function() {
          console.log(this.hasOwnProperty('notoptional')) // true
          console.log(this.hasOwnProperty('optional')) // false
        }
      }
    }
  })
 *```
 *
 *
 * ##### Combining directives with different scope defintions
 *
 * In general it's possible to apply more than one directive to one element, but there might be limitations
 * depending on the type of scope required by the directives. The following points will help explain these limitations.
 * For simplicity only two directives are taken into account, but it is also applicable for several directives:
 *
 * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
 * * **child scope** + **no scope** =>  Both directives will share one single child scope
 * * **child scope** + **child scope** =>  Both directives will share one single child scope
 * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
 * its parent's scope
 * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
 * be applied to the same element.
 * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
 * cannot be applied to the same element.
 *
 *
 * #### `bindToController`
 * This property is used to bind scope properties directly to the controller. It can be either
 * `true` or an object hash with the same format as the `scope` property.
 *
 * When an isolate scope is used for a directive (see above), `bindToController: true` will
 * allow a component to have its properties bound to the controller, rather than to scope.
 *
 * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
 * properties. You can access these bindings once they have been initialized by providing a controller method called
 * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
 * initialized.
 *
 * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
 * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
 * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
 * scope (useful for component directives).
 *
 * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
 *
 *
 * #### `controller`
 * Controller constructor function. The controller is instantiated before the
 * pre-linking phase and can be accessed by other directives (see
 * `require` attribute). This allows the directives to communicate with each other and augment
 * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
 *
 * * `$scope` - Current scope associated with the element
 * * `$element` - Current element
 * * `$attrs` - Current attributes object for the element
 * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
 *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
 *    * `scope`: (optional) override the scope.
 *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
 *    * `futureParentElement` (optional):
 *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
 *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
 *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
 *          and when the `cloneLinkingFn` is passed,
 *          as those elements need to created and cloned in a special way when they are defined outside their
 *          usual containers (e.g. like `<svg>`).
 *        * See also the `directive.templateNamespace` property.
 *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
 *      then the default transclusion is provided.
 *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
 *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
 *
 * #### `require`
 * Require another directive and inject its controller as the fourth argument to the linking function. The
 * `require` property can be a string, an array or an object:
 * * a **string** containing the name of the directive to pass to the linking function
 * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
 * linking function will be an array of controllers in the same order as the names in the `require` property
 * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
 * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
 * controllers.
 *
 * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
 * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
 * have been constructed but before `$onInit` is called.
 * If the name of the required controller is the same as the local name (the key), the name can be
 * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
 * See the {@link $compileProvider#component} helper for an example of how this can be used.
 * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
 * raised (unless no link function is specified and the required controllers are not being bound to the directive
 * controller, in which case error checking is skipped). The name can be prefixed with:
 *
 * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
 * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
 * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
 * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
 * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
 *   `null` to the `link` fn if not found.
 * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
 *   `null` to the `link` fn if not found.
 *
 *
 * #### `controllerAs`
 * Identifier name for a reference to the controller in the directive's scope.
 * This allows the controller to be referenced from the directive template. This is especially
 * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
 * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
 * `controllerAs` reference might overwrite a property that already exists on the parent scope.
 *
 *
 * #### `restrict`
 * String of subset of `EACM` which restricts the directive to a specific directive
 * declaration style. If omitted, the defaults (elements and attributes) are used.
 *
 * * `E` - Element name (default): `<my-directive></my-directive>`
 * * `A` - Attribute (default): `<div my-directive="exp"></div>`
 * * `C` - Class: `<div class="my-directive: exp;"></div>`
 * * `M` - Comment: `<!-- directive: my-directive exp -->`
 *
 *
 * #### `templateNamespace`
 * String representing the document type used by the markup in the template.
 * AngularJS needs this information as those elements need to be created and cloned
 * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
 *
 * * `html` - All root nodes in the template are HTML. Root nodes may also be
 *   top-level elements such as `<svg>` or `<math>`.
 * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
 * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
 *
 * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
 *
 * #### `template`
 * HTML markup that may:
 * * Replace the contents of the directive's element (default).
 * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
 * * Wrap the contents of the directive's element (if `transclude` is true).
 *
 * Value may be:
 *
 * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
 * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
 *   function api below) and returns a string value.
 *
 *
 * #### `templateUrl`
 * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
 *
 * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
 * for later when the template has been resolved.  In the meantime it will continue to compile and link
 * sibling and parent elements as though this element had not contained any directives.
 *
 * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
 * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
 * case when only one deeply nested directive has `templateUrl`.
 *
 * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
 *
 * You can specify `templateUrl` as a string representing the URL or as a function which takes two
 * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
 * a string value representing the url.  In either case, the template URL is passed through {@link
 * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
 *
 *
 * #### `replace`
 * <div class="alert alert-danger">
 * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+).
 * </div>
 *
 * Specifies what the template should replace. Defaults to `false`.
 *
 * * `true` - the template will replace the directive's element.
 * * `false` - the template will replace the contents of the directive's element.
 *
 * The replacement process migrates all of the attributes / classes from the old element to the new
 * one. See the {@link guide/directive#template-expanding-directive
 * Directives Guide} for an example.
 *
 * There are very few scenarios where element replacement is required for the application function,
 * the main one being reusable custom components that are used within SVG contexts
 * (because SVG doesn't work with custom elements in the DOM tree).
 *
 * #### `transclude`
 * Extract the contents of the element where the directive appears and make it available to the directive.
 * The contents are compiled and provided to the directive as a **transclusion function**. See the
 * {@link $compile#transclusion Transclusion} section below.
 *
 *
 * #### `compile`
 *
 * ```js
 *   function compile(tElement, tAttrs, transclude) { ... }
 * ```
 *
 * The compile function deals with transforming the template DOM. Since most directives do not do
 * template transformation, it is not used often. The compile function takes the following arguments:
 *
 *   * `tElement` - template element - The element where the directive has been declared. It is
 *     safe to do template transformation on the element and child elements only.
 *
 *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
 *     between all directive compile functions.
 *
 *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
 *
 * <div class="alert alert-warning">
 * **Note:** The template instance and the link instance may be different objects if the template has
 * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
 * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
 * should be done in a linking function rather than in a compile function.
 * </div>

 * <div class="alert alert-warning">
 * **Note:** The compile function cannot handle directives that recursively use themselves in their
 * own templates or compile functions. Compiling these directives results in an infinite loop and
 * stack overflow errors.
 *
 * This can be avoided by manually using $compile in the postLink function to imperatively compile
 * a directive's template instead of relying on automatic template compilation via `template` or
 * `templateUrl` declaration or manual compilation inside the compile function.
 * </div>
 *
 * <div class="alert alert-danger">
 * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
 *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
 *   to the link function instead.
 * </div>

 * A compile function can have a return value which can be either a function or an object.
 *
 * * returning a (post-link) function - is equivalent to registering the linking function via the
 *   `link` property of the config object when the compile function is empty.
 *
 * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
 *   control when a linking function should be called during the linking phase. See info about
 *   pre-linking and post-linking functions below.
 *
 *
 * #### `link`
 * This property is used only if the `compile` property is not defined.
 *
 * ```js
 *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
 * ```
 *
 * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
 * executed after the template has been cloned. This is where most of the directive logic will be
 * put.
 *
 *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
 *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
 *
 *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
 *     manipulate the children of the element only in `postLink` function since the children have
 *     already been linked.
 *
 *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
 *     between all directive linking functions.
 *
 *   * `controller` - the directive's required controller instance(s) - Instances are shared
 *     among all directives, which allows the directives to use the controllers as a communication
 *     channel. The exact value depends on the directive's `require` property:
 *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
 *       * `string`: the controller instance
 *       * `array`: array of controller instances
 *
 *     If a required controller cannot be found, and it is optional, the instance is `null`,
 *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
 *
 *     Note that you can also require the directive's own controller - it will be made available like
 *     any other controller.
 *
 *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
 *     This is the same as the `$transclude` parameter of directive controllers,
 *     see {@link ng.$compile#-controller- the controller section for details}.
 *     `function([scope], cloneLinkingFn, futureParentElement)`.
 *
 * #### Pre-linking function
 *
 * Executed before the child elements are linked. Not safe to do DOM transformation since the
 * compiler linking function will fail to locate the correct elements for linking.
 *
 * #### Post-linking function
 *
 * Executed after the child elements are linked.
 *
 * Note that child elements that contain `templateUrl` directives will not have been compiled
 * and linked since they are waiting for their template to load asynchronously and their own
 * compilation and linking has been suspended until that occurs.
 *
 * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
 * for their async templates to be resolved.
 *
 *
 * ### Transclusion
 *
 * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
 * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
 * scope from where they were taken.
 *
 * Transclusion is used (often with {@link ngTransclude}) to insert the
 * original contents of a directive's element into a specified place in the template of the directive.
 * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
 * content has access to the properties on the scope from which it was taken, even if the directive
 * has isolated scope.
 * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
 *
 * This makes it possible for the widget to have private state for its template, while the transcluded
 * content has access to its originating scope.
 *
 * <div class="alert alert-warning">
 * **Note:** When testing an element transclude directive you must not place the directive at the root of the
 * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
 * Testing Transclusion Directives}.
 * </div>
 *
 * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
 * directive's element, the entire element or multiple parts of the element contents:
 *
 * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
 * * `'element'` - transclude the whole of the directive's element including any directives on this
 *   element that defined at a lower priority than this directive. When used, the `template`
 *   property is ignored.
 * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
 *
 * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
 *
 * This object is a map where the keys are the name of the slot to fill and the value is an element selector
 * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
 * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
 *
 * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
 *
 * If the element selector is prefixed with a `?` then that slot is optional.
 *
 * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
 * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
 *
 * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
 * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
 * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
 * injectable into the directive's controller.
 *
 *
 * #### Transclusion Functions
 *
 * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
 * function** to the directive's `link` function and `controller`. This transclusion function is a special
 * **linking function** that will return the compiled contents linked to a new transclusion scope.
 *
 * <div class="alert alert-info">
 * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
 * ngTransclude will deal with it for us.
 * </div>
 *
 * If you want to manually control the insertion and removal of the transcluded content in your directive
 * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
 * object that contains the compiled DOM, which is linked to the correct transclusion scope.
 *
 * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
 * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
 * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
 *
 * <div class="alert alert-info">
 * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
 * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
 * </div>
 *
 * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
 * attach function**:
 *
 * ```js
 * var transcludedContent, transclusionScope;
 *
 * $transclude(function(clone, scope) {
 *   element.append(clone);
 *   transcludedContent = clone;
 *   transclusionScope = scope;
 * });
 * ```
 *
 * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
 * associated transclusion scope:
 *
 * ```js
 * transcludedContent.remove();
 * transclusionScope.$destroy();
 * ```
 *
 * <div class="alert alert-info">
 * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
 * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
 * then you are also responsible for calling `$destroy` on the transclusion scope.
 * </div>
 *
 * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
 * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
 * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
 *
 *
 * #### Transclusion Scopes
 *
 * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
 * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
 * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
 * was taken.
 *
 * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
 * like this:
 *
 * ```html
 * <div ng-app>
 *   <div isolate>
 *     <div transclusion>
 *     </div>
 *   </div>
 * </div>
 * ```
 *
 * The `$parent` scope hierarchy will look like this:
 *
   ```
   - $rootScope
     - isolate
       - transclusion
   ```
 *
 * but the scopes will inherit prototypically from different scopes to their `$parent`.
 *
   ```
   - $rootScope
     - transclusion
   - isolate
   ```
 *
 *
 * ### Attributes
 *
 * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
 * `link()` or `compile()` functions. It has a variety of uses.
 *
 * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
 *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
 *   to the attributes.
 *
 * * *Directive inter-communication:* All directives share the same instance of the attributes
 *   object which allows the directives to use the attributes object as inter directive
 *   communication.
 *
 * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
 *   allowing other directives to read the interpolated value.
 *
 * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
 *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
 *   the only way to easily get the actual value because during the linking phase the interpolation
 *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
 *
 * ```js
 * function linkingFn(scope, elm, attrs, ctrl) {
 *   // get the attribute value
 *   console.log(attrs.ngModel);
 *
 *   // change the attribute
 *   attrs.$set('ngModel', 'new value');
 *
 *   // observe changes to interpolated attribute
 *   attrs.$observe('ngModel', function(value) {
 *     console.log('ngModel has changed value to ' + value);
 *   });
 * }
 * ```
 *
 * ## Example
 *
 * <div class="alert alert-warning">
 * **Note**: Typically directives are registered with `module.directive`. The example below is
 * to illustrate how `$compile` works.
 * </div>
 *
 <example module="compileExample" name="compile">

        // factory function. The factory function injects the '$compile'
        $compileProvider.directive('compile', function($compile) {
          // directive factory creates a link function

 * </div>
 *
 * @param {number} maxPriority only apply directives lower than given priority (Only effects the
 *                 root element(s), not their children)
 * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
 * (a DOM element/tree) to a scope. Where:
 *
 *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
 *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
 *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
 *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
 *  called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
 *
 *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
 *      * `scope` - is the current scope with which the linking function is working with.
 *
 *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
 *  keys may be used to control linking behavior:
 *
 *      * `parentBoundTranscludeFn` - the transclude function made available to
 *        directives; if given, it will be passed through to the link functions of
 *        directives found in `element` during compilation.
 *      * `transcludeControllers` - an object hash with keys that map controller names
 *        to a hash with the key `instance`, which maps to the controller instance;
 *        if given, it will make the controllers available to directives on the compileNode:
 *        ```
 *        {
 *          parent: {
 *            instance: parentControllerInstance
 *          }
 *        }
 *        ```
 *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
 *        the cloned elements; only needed for transcludes that are allowed to contain non html
 *        elements (e.g. SVG elements). See also the directive.controller property.
 *
 * Calling the linking function returns the element of the template. It is either the original
 * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
 *
 * After linking the view is not updated until after a call to $digest which typically is done by
 * AngularJS automatically.
 *
 * If you need access to the bound view, there are two ways to do it:
 *
 * - If you are not asking the linking function to clone the template, create the DOM element(s)
 *   before you send them to the compiler and keep this reference around.
 *   ```js
 *     var element = $compile('<p>{{total}}</p>')(scope);
 *   ```
 *
 * - if on the other hand, you need the element to be cloned, the view reference from the original
 *   example would not point to the clone, but rather to the original template that was cloned. In
 *   this case, you can access the clone via the cloneAttachFn:
 *   ```js
 *     var templateElement = angular.element('<p>{{total}}</p>'),
 *         scope = ....;
 *
 *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
 *       //attach the clone to DOM document at the right place
 *     });
 *
 *     //now we have reference to the cloned DOM via `clonedElement`
 *   ```
 *
 *
 * For information on how the compiler works, see the
 * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide.

 * ### Double Compilation
 *
   Double compilation occurs when an already compiled part of the DOM gets

   ### Issues with `replace: true`
 *
 * <div class="alert alert-danger">
 *   **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use,
 *   mainly due to the issues listed here. It has been completely removed in the new Angular.
 * </div>
 *
 * #### Attribute values are not merged
 *
 * When a `replace` directive encounters the same attribute on the original and the replace node,
 * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of
 * the `style` attribute.
 * ```html
 * Original Node: <span class="original" style="color: red;"></span>
 * Replace Template: <span class="replaced" style="background: blue;"></span>
 * Result: <span class="original replaced" style="color: red; background: blue;"></span>
 * ```
 *
 * That means attributes that contain AngularJS expressions will not be merged correctly, e.g.
 * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error:
 *
 * ```html
 * Original Node: <span ng-class="{'something': something}" ng-show="!condition"></span>
 * Replace Template: <span ng-class="{'else': else}" ng-show="otherCondition"></span>
 * Result: <span ng-class="{'something': something} {'else': else}" ng-show="!condition otherCondition"></span>
 * ```
 *
 * See issue [#5695](https://github.com/angular/angular.js/issues/5695).
 *
 * #### Directives are not deduplicated before compilation
 *
 * When the original node and the replace template declare the same directive(s), they will be
 * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler
 * does not deduplicate them. In many cases, this is not noticable, but e.g. {@link ngModel} will
 * attach `$formatters` and `$parsers` twice.
 *
 * See issue [#2573](https://github.com/angular/angular.js/issues/2573).
 *
 * #### `transclude: element` in the replace template root can have unexpected effects
 *
 * When the replace template has a directive at the root node that uses
 * {@link $compile#-transclude- `transclude: element`}, e.g.
 * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect.
 * See the following issues:
 *
 * - Incorrect scope on replaced element:
 * [#9837](https://github.com/angular/angular.js/issues/9837)
 * - Different DOM between `template` and `templateUrl`:
 * [#10612](https://github.com/angular/angular.js/issues/14326)

/**
 * @ngdoc directive
 * @name ngProp
 * @restrict A
 * @element ANY
 *
 * @usage
 *
 * ```html
 * <ANY ng-prop-propname="expression">
 * </ANY>
 * ```
 *
 * or with uppercase letters in property (e.g. "propName"):
 *
 *
 * ```html
 * <ANY ng-prop-prop_name="expression">
 * </ANY>
 * ```
 *
 *
 * @description
 * The `ngProp` directive binds an expression to a DOM element property.
 * `ngProp` allows writing to arbitrary properties by including
 * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to
 * the `value` property.
 *
 * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives
 * handle the most common use cases (instead of the above example, you would use {@link ngValue}).
 *
 * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements)
 * often use custom properties to hold data, and `ngProp` can be used to provide input to these
 * custom elements.
 *
 * ## Binding to camelCase properties
 *
 * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped.
 * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
 * `innerHTML`  must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an
 * example, and for binding HTML {@link ngBindHtml} should be used.
 *
 * ## Security
 *
 * Binding expressions to arbitrary properties poses a security risk, as  properties like `innerHTML`
 * can insert potentially dangerous HTML into the application, e.g. script tags that execute
 * malicious code.
 * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}.
 * This means vulnerable properties require their content to be "trusted", based on the
 * context of the property. For example, the `innerHTML` is in the `HTML` context, and the
 * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to
 * this property are trusted as a `RESOURCE_URL`.
 *
 * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is
 * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for
 * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al.
 *
 * In some cases you can also rely upon automatic sanitization of untrusted values - see below.
 *
 * Based on the context, other options may exist to mark a value as trusted / configure the behavior
 * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use
 * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()}
 * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}.
 *
 * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}.
 *
 * ### HTML Sanitization
 *
 * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the
 * content.
 * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the
 * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to
 * `innerHTML`.
 *

 *           this.unsafeContent = '<button onclick="alert(\'Hello XSS!\')">Click for XSS</button>';
 *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);

 * or with uppercase letters in property (e.g. "eventName"):
 *
 *
 * ```html
 * <ANY ng-on-event_name="expression">

 * ```
 *
 * @description
 * The `ngOn` directive adds an event listener to a DOM element via
 * {@link angular.element angular.element().on()}, and evaluates an expression when the event is
 * fired.
 * `ngOn` allows adding listeners for arbitrary events by including
 * the event name in the attribute, e.g. `ng-on-drop="onDrop()"` executes the 'onDrop()' expression
 * when the `drop` event is fired.
 *
 * AngularJS provides specific directives for many events, such as {@link ngClick}, so in most
 * cases it is not necessary to use `ngOn`. However, AngularJS does not support all events
 * (e.g. the `drop` event in the example above), and new events might be introduced in later DOM
 * standards.
 *
 * Another use-case for `ngOn` is listening to
 * [custom events](https://developer.mozilla.org/docs/Web/Guide/Events/Creating_and_triggering_events)
 * fired by
 * [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements).
 *
 * ## Binding to camelCase properties
 *
 * Since HTML attributes are case-insensitive, camelCase properties like `myEvent` must be escaped.
 * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
 * `myEvent` must be written as `ng-on-my_event="expression"`.

   *    - `controller` – `{(string|function()=}` – controller constructor function that should be
   *      associated with newly created scope or the name of a {@link ng.$compile#-controller-
   *      registered controller} if passed as a string. An empty `noop` function by default.
   *    - `controllerAs` – `{string=}` – identifier name for to reference the controller in the component's scope.
   *      If present, the controller will be published to scope under the `controllerAs` name.
   *      If not present, this will default to be `$ctrl`.
   *    - `template` – `{string=|function()=}` – html template as a string or a function that
   *      returns an html template as a string which should be used as the contents of this component.
   *      Empty string by default.
   *
   *      If `template` is a function, then it is {@link auto.$injector#invoke injected} with
   *      the following locals:
   *
   *      - `$element` - Current element
   *      - `$attrs` - Current attributes object for the element
   *
   *    - `templateUrl` – `{string=|function()=}` – path or function that returns a path to an html
   *      template that should be used  as the contents of this component.
   *
   *      If `templateUrl` is a function, then it is {@link auto.$injector#invoke injected} with
   *      the following locals:
   *
   *      - `$element` - Current element
   *      - `$attrs` - Current attributes object for the element
   *
   *    - `bindings` – `{object=}` – defines bindings between DOM attributes and component properties.
   *      Component properties are always bound to the component controller and not to the scope.
   *      See {@link ng.$compile#-bindtocontroller- `bindToController`}.
   *    - `transclude` – `{boolean=}` – whether {@link $compile#transclusion content transclusion} is enabled.
   *      Disabled by default.
   *    - `require` - `{Object<string, string>=}` - requires the controllers of other directives and binds them to
   *      this component's controller. The object keys specify the property names under which the required
   *      controllers (object values) will be bound. See {@link ng.$compile#-require- `require`}.
   *    - `$...` – additional properties to attach to the directive factory function and the controller
   *      constructor function. (This is used by the component router to annotate)
   *
   * @returns {ng.$compileProvider} the compile provider itself, for chaining of function calls.
   * @description
   * Register a **component definition** with the compiler. This is a shorthand for registering a special
   * type of directive, which represents a self-contained UI component in your application. Such components
   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
   *
   * Component definitions are very simple and do not require as much configuration as defining general
   * directives. Component definitions usually consist only of a template and a controller backing it.
   *
   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
   * `bindToController`. They always have **isolate scope** and are restricted to elements.
   *
   * Here are a few examples of how you would usually define components:
   *
   * ```js
   *   var myMod = angular.module(...);
   *   myMod.component('myComp', {
   *     template: '<div>My name is {{$ctrl.name}}</div>',
   *     controller: function() {
   *       this.name = 'shahar';
   *     }
   *   });
   *
   *   myMod.component('myComp', {
   *     template: '<div>My name is {{$ctrl.name}}</div>',
   *     bindings: {name: '@'}
   *   });
   *
   *   myMod.component('myComp', {
   *     templateUrl: 'views/my-comp.html',
   *     controller: 'MyCtrl',
   *     controllerAs: 'ctrl',
   *     bindings: {name: '@'}
   *   });
   *
   * ```
   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.
   *
   * <br />
   * See also {@link ng.$compileProvider#directive $compileProvider.directive()}.

     * @description
     * The `$http` service is a core AngularJS service that facilitates communication with the remote
     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
     *
     * For unit testing applications that use `$http` service, see
     * {@link ngMock.$httpBackend $httpBackend mock}.
     *
     * For a higher level of abstraction, please check out the {@link ngResource.$resource
     * $resource} service.
     *
     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
     * it is important to familiarize yourself with these APIs and the guarantees they provide.
     *
     *
     * ## General usage
     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
     * that is used to generate an HTTP request and returns  a {@link ng.$q promise} that is
     * resolved (request success) or rejected (request failure) with a
     * {@link ng.$http#$http-returns response} object.
     *
     * ```js
     *   // Simple GET request example:
     *   $http({
     *     method: 'GET',
     *     url: '/someUrl'
     *   }).then(function successCallback(response) {
     *       // this callback will be called asynchronously
     *       // when the response is available
     *     }, function errorCallback(response) {
     *       // called asynchronously if an error occurs
     *       // or server returns response with an error status.
     *     });
     * ```
     *
     *
     * ## Shortcut methods
     *
     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
     * last argument.
     *
     * ```js
     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
     * ```
     *
     * Complete list of shortcut methods:
     *
     * - {@link ng.$http#get $http.get}
     * - {@link ng.$http#head $http.head}
     * - {@link ng.$http#post $http.post}
     * - {@link ng.$http#put $http.put}
     * - {@link ng.$http#delete $http.delete}
     * - {@link ng.$http#jsonp $http.jsonp}
     * - {@link ng.$http#patch $http.patch}
     *
     *
     * ## Writing Unit Tests that use $http
     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
     * request using trained responses.
     *
     * ```
     * $httpBackend.expectGET(...);
     * $http.get(...);
     * $httpBackend.flush();
     * ```
     *
     * ## Setting HTTP Headers
     *
     * The $http service will automatically add certain HTTP headers to all requests. These defaults
     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
     * object, which currently contains this default configuration:
     *
     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
     *   - <code>Accept: application/json, text/plain, \*&#65279;/&#65279;\*</code>
     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
     *   - `Content-Type: application/json`
     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
     *   - `Content-Type: application/json`
     *
     * To add or overwrite these defaults, simply add or remove a property from these configuration
     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
     * with the lowercased HTTP method name as the key, e.g.
     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
     *
     * The defaults can also be set at runtime via the `$http.defaults` object in the same
     * fashion. For example:
     *
     * ```
     * module.run(function($http) {
     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
     * });
     * ```
     *
     * In addition, you can supply a `headers` property in the config object passed when
     * calling `$http(config)`, which overrides the defaults without changing them globally.
     *
     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
     * Use the `headers` property, setting the desired header to `undefined`. For example:
     *
     * ```js
     * var req = {
     *  method: 'POST',
     *  url: 'http://example.com',
     *  headers: {
     *    'Content-Type': undefined
     *  },
     *  data: { test: 'test' }
     * }
     *
     * $http(req).then(function(){...}, function(){...});
     * ```
     *
     * ## Transforming Requests and Responses
     *
     * Both requests and responses can be transformed using transformation functions: `transformRequest`
     * and `transformResponse`. These properties can be a single function that returns
     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
     *
     * <div class="alert alert-warning">
     * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
     * function will be reflected on the scope and in any templates where the object is data-bound.
     * To prevent this, transform functions should have no side-effects.
     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
     * </div>
     *
     * ### Default Transformations
     *
     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
     * `defaults.transformResponse` properties. If a request does not provide its own transformations
     * then these will be applied.
     *
     * You can augment or replace the default transformations by modifying these properties by adding to or
     * replacing the array.
     *
     * AngularJS provides the following default transformations:
     *
     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is
     * an array with one function that does the following:
     *
     * - If the `data` property of the request configuration object contains an object, serialize it
     *   into JSON format.
     *
     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is
     * an array with one function that does the following:
     *
     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
     *  - If the `Content-Type` is `application/json` or the response looks like JSON,
   *      deserialize it using a JSON parser.
     *
     *
     * ### Overriding the Default Transformations Per Request
     *
     * If you wish to override the request/response transformations only for a single request then provide
     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
     * into `$http`.
     *
     * Note that if you provide these properties on the config object the default transformations will be
     * overwritten. If you wish to augment the default transformations then you must include them in your
     * local transformation array.
     *
     * The following code demonstrates adding a new response transformation to be run after the default response
     * transformations have been run.
     *
     * ```js
     * function appendTransform(defaults, transform) {
     *
     *   // We can't guarantee that the default transformation is an array
     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
     *
     *   // Append the new transformation to the defaults
     *   return defaults.concat(transform);
     * }
     *
     * $http({
     *   url: '...',
     *   method: 'GET',
     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
     *     return doTransform(value);
     *   })
     * });
     * ```
     *
     *
     * ## Caching
     *
     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
     * set the config.cache value or the default cache value to TRUE or to a cache object (created
     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
     * precedence over the default cache value.
     *
     * In order to:
     *   * cache all responses - set the default cache value to TRUE or to a cache object
     *   * cache a specific response - set config.cache value to TRUE or to a cache object
     *
     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
     * then the default `$cacheFactory("$http")` object is used.
     *
     * The default cache value can be set by updating the
     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
     *
     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
     * the relevant cache object. The next time the same request is made, the response is returned
     * from the cache without sending a request to the server.
     *
     * Take note that:
     *
     *   * Only GET and JSONP requests are cached.
     *   * The cache key is the request URL including search parameters; headers are not considered.
     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
     *   * If multiple identical requests are made using the same cache, which is not yet populated,
     *     one request will be made to the server and remaining requests will return the same response.
     *   * A cache-control header on the response does not affect if or how responses are cached.
     *
     *
     * ## Interceptors
     *
     * Before you start creating interceptors, be sure to understand the
     * {@link ng.$q $q and deferred/promise APIs}.
     *
     * For purposes of global error handling, authentication, or any kind of synchronous or
     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
     * able to intercept requests before they are handed to the server and
     * responses before they are handed over to the application code that
     * initiated these requests. The interceptors leverage the {@link ng.$q
     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
     *
     * The interceptors are service factories that are registered with the `$httpProvider` by
     * adding them to the `$httpProvider.interceptors` array. The factory is called and
     * injected with dependencies (if specified) and returns the interceptor.
     *
     * There are two kinds of interceptors (and two kinds of rejection interceptors):
     *
     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
     *     modify the `config` object or create a new one. The function needs to return the `config`
     *     object directly, or a promise containing the `config` or a new `config` object.
     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
     *     resolved with a rejection.
     *   * `response`: interceptors get called with http `response` object. The function is free to
     *     modify the `response` object or create a new one. The function needs to return the `response`
     *     object directly, or as a promise containing the `response` or a new `response` object.
     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
     *     resolved with a rejection.
     *
     *
     * ```js
     *   // register the interceptor as a service
     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
     *     return {
     *       // optional method
     *       'request': function(config) {
     *         // do something on success
     *         return config;
     *       },
     *
     *       // optional method
     *      'requestError': function(rejection) {
     *         // do something on error
     *         if (canRecover(rejection)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(rejection);
     *       },
     *
     *
     *
     *       // optional method
     *       'response': function(response) {
     *         // do something on success
     *         return response;
     *       },
     *
     *       // optional method
     *      'responseError': function(rejection) {
     *         // do something on error
     *         if (canRecover(rejection)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(rejection);
     *       }
     *     };
     *   });
     *
     *   $httpProvider.interceptors.push('myHttpInterceptor');
     *
     *
     *   // alternatively, register the interceptor via an anonymous factory
     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
     *     return {
     *      'request': function(config) {
     *          // same as above
     *       },
     *
     *       'response': function(response) {
     *          // same as above
     *       }
     *     };
     *   });
     * ```
     *
     * ## Security Considerations
     *
     * When designing web applications, consider security threats from:
     *
     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
     *
     * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes
     * pre-configured with strategies that address these issues, but for this to work backend server
     * cooperation is required.
     *
     * ### JSON Vulnerability Protection
     *
     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
     * allows third party website to turn your JSON resource URL into
     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
     * AngularJS will automatically strip the prefix before processing it as JSON.
     *
     * For example if your server needs to return:
     * ```js
     * ['one','two']
     * ```
     *
     * which is vulnerable to attack, your server can return:
     * ```js
     * )]}',
     * ['one','two']
     * ```
     *
     * AngularJS will strip the prefix, before processing the JSON.
     *
     *
     * ### Cross Site Request Forgery (XSRF) Protection
     *
     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
     * which the attacker can trick an authenticated user into unknowingly executing actions on your
     * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the
     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
     * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read
     * the cookie, your server can be assured that the XHR came from JavaScript running on your
     * domain.
     *
     * To take advantage of this, your server needs to set a token in a JavaScript readable session
     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
     * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be
     * sure that only JavaScript running on your domain could have sent the request. The token must
     * be unique for each user and must be verifiable by the server (to prevent the JavaScript from
     * making up its own tokens). We recommend that the token is a digest of your site's
     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
     * for added security.
     *
     * The header will &mdash; by default &mdash; **not** be set for cross-domain requests. This
     * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining
     * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you
     * want to, you can whitelist additional origins to also receive the XSRF token, by adding them
     * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be
     * useful, for example, if your application, served from `example.com`, needs to access your API
     * at `api.example.com`.
     * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for
     * more details.
     *
     * <div class="alert alert-danger">
     *   **Warning**<br />
     *   Only whitelist origins that you have control over and make sure you understand the
     *   implications of doing so.
     * </div>
     *
     * The name of the cookie and the header can be specified using the `xsrfCookieName` and
     * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time,
     * `$http.defaults` at run-time, or the per-request config object.
     *
     * In order to prevent collisions in environments where multiple AngularJS apps share the
     * same domain or subdomain, we recommend that each application uses a unique cookie name.
     *
     *
     * @param {object} config Object describing the request to be made and how it should be
     *    processed. The object has following properties:
     *
     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
     *    - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
     *      or an object created by a call to `$sce.trustAsResourceUrl(url)`.
     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
     *      with the `paramSerializer` and appended as GET parameters.
     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
     *      HTTP headers to send to the server. If the return value of a function is null, the
     *      header will not be sent. Functions accept a config object as an argument.
     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
     *      The handler will be called in the context of a `$apply` block.
     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
     *      The handler will be called in the context of a `$apply` block.
     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
     *    - **transformRequest** –
     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      request body and headers and returns its transformed (typically serialized) version.
     *      See {@link ng.$http#overriding-the-default-transformations-per-request
     *      Overriding the Default Transformations}
     *    - **transformResponse** –
     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      response body, headers and status and returns its transformed (typically deserialized) version.
     *      See {@link ng.$http#overriding-the-default-transformations-per-request
     *      Overriding the Default Transformations}
     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
     *      prepare the string representation of request parameters (specified as an object).
     *      If specified as string, it is interpreted as function registered with the
     *      {@link $injector $injector}, which means you can create your own serializer
     *      by registering it as a {@link auto.$provide#service service}.
     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
     *      See {@link $http#caching $http Caching} for more information.
     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
     *      that should abort the request when resolved.
     *
     *      A numerical timeout or a promise returned from {@link ng.$timeout $timeout}, will set
     *      the `xhrStatus` in the {@link $http#$http-returns response} to "timeout", and any other
     *      resolved promise will set it to "abort", following standard XMLHttpRequest behavior.
     *
     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
     *      for more information.
     *    - **responseType** - `{string}` - see
     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
     *
     * @returns {HttpPromise} A {@link ng.$q `Promise}` that will be resolved (request success)
     *   or rejected (request failure) with a response object.
     *
     *   The response object has these properties:
     *
     *   - **data** – `{string|Object}` – The response body transformed with
     *     the transform functions.
     *   - **status** – `{number}` – HTTP status code of the response.
     *   - **headers** – `{function([headerName])}` – Header getter function.
     *   - **config** – `{Object}` – The configuration object that was used
     *     to generate the request.
     *   - **statusText** – `{string}` – HTTP status text of the response.
     *   - **xhrStatus** – `{string}` – Status of the XMLHttpRequest
     *     (`complete`, `error`, `timeout` or `abort`).
     *
     *
     *   A response status code between 200 and 299 is considered a success status
     *   and will result in the success callback being called. Any response status
     *   code outside of that range is considered an error status and will result
     *   in the error callback being called.
     *   Also, status codes less than -1 are normalized to zero. -1 usually means
     *   the request was aborted, e.g. using a `config.timeout`. More information
     *   about the status might be available in the `xhrStatus` property.
     *
     *   Note that if the response is a redirect, XMLHttpRequest will transparently
     *   follow it, meaning that the outcome (success or error) will be determined
     *   by the final response status code.
     *
     *
     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
     *   requests. This is primarily meant to be used for debugging purposes.

     * Shortcut method to perform `JSONP` request.
     *
     * Note that, since JSONP requests are sensitive because the response is given full access to the browser,
     * the url must be declared, via {@link $sce} as a trusted resource URL.
     * You can trust a URL by adding it to the whitelist via
     * {@link $sceDelegateProvider#resourceUrlWhitelist  `$sceDelegateProvider.resourceUrlWhitelist`} or
     * by explicitly trusting the URL via {@link $sce#trustAsResourceUrl `$sce.trustAsResourceUrl(url)`}.
     *
     * You should avoid generating the URL for the JSONP request from user provided data.
     * Provide additional query parameters via `params` property of the `config` parameter, rather than
     * modifying the URL itself.
     *
     * JSONP requests must specify a callback to be used in the response from the server. This callback
     * is passed as a query parameter in the request. You must specify the name of this parameter by
     * setting the `jsonpCallbackParam` property on the request config object.
     *
     * ```
     * $http.jsonp('some/trusted/url', {jsonpCallbackParam: 'callback'})
     * ```
     *
     * You can also specify a default callback parameter name in `$http.defaults.jsonpCallbackParam`.
     * Initially this is set to `'callback'`.
     *
     * <div class="alert alert-danger">
     * You can no longer use the `JSON_CALLBACK` string as a placeholder for specifying where the callback
     * parameter value should go.
     * </div>

     * If you would like to customise where and how the callbacks are stored then try overriding
     * or decorating the {@link $jsonpCallbacks} service.

     *
     * @description
     *
     * Compiles a string with markup into an interpolation function. This service is used by the
     * HTML {@link ng.$compile $compile} service for data binding. See
     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
     * interpolation markup.
     *
     *
     * ```js
     *   var $interpolate = ...; // injected
     *   var exp = $interpolate('Hello {{name | uppercase}}!');
     *   expect(exp({name:'AngularJS'})).toEqual('Hello ANGULARJS!');
     * ```
     *
     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
     * `true`, the interpolation function will return `undefined` unless all embedded expressions
     * evaluate to a value other than `undefined`.
     *
     * ```js
     *   var $interpolate = ...; // injected
     *   var context = {greeting: 'Hello', name: undefined };
     *
     *   // default "forgiving" mode
     *   var exp = $interpolate('{{greeting}} {{name}}!');
     *   expect(exp(context)).toEqual('Hello !');
     *
     *   // "allOrNothing" mode

     *   expect(exp(context)).toBeUndefined();
     *   context.name = 'AngularJS';
     *   expect(exp(context)).toEqual('Hello AngularJS!');
     * ```
     *
     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
     *
     * #### Escaped Interpolation
     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
     * or binding.
     *
     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
     * degree, while also enabling code examples to work without relying on the
     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
     *
     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
     * interpolation start/end markers with their escaped counterparts.**
     *
     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
     * output when the $interpolate service processes the text. So, for HTML elements interpolated
     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
     * this is typically useful only when user-data is used in rendering a template from the server, or
     * when otherwise untrusted data is used by a directive.
     *
     * <example name="interpolation">
     *  <file name="index.html">
     *    <div ng-init="username='A user'">
     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
     *        </p>
     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
     *        application, but fails to accomplish their task, because the server has correctly
     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
     *        characters.</p>
     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
     *        from the database by an administrator.</p>
     *    </div>
     *  </file>
     * </example>
     *
     * @knownIssue
     * It is currently not possible for an interpolated expression to contain the interpolation end
     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
     *
     * @knownIssue
     * All directives and components must use the standard `{{` `}}` interpolation symbols
     * in their templates. If you change the application interpolation symbols the {@link $compile}
     * service will attempt to denormalize the standard symbols to the custom symbols.
     * The denormalization process is not clever enough to know not to replace instances of the standard
     * symbols where they would not normally be treated as interpolation symbols. For example in the following
     * code snippet the closing braces of the literal object will get incorrectly denormalized:
     *
     * ```
     * <div data-context='{"context":{"id":3,"type":"page"}}">
     * ```
     *
     * The workaround is to ensure that such instances are separated by whitespace:
     * ```
     * <div data-context='{"context":{"id":3,"type":"page"} }">
     * ```

     * @description
     * AngularJS's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
     * milliseconds.
     *
     * The return value of registering an interval function is a promise. This promise will be
     * notified upon each tick of the interval, and will be resolved after `count` iterations, or
     * run indefinitely if `count` is not defined. The value of the notification will be the
     * number of iterations that have run.
     * To cancel an interval, call `$interval.cancel(promise)`.
     *
     * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
     * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
     * time.
     *
     * <div class="alert alert-warning">
     * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
     * with them.  In particular they are not automatically destroyed when a controller's scope or a
     * directive's element are destroyed.
     * You should take this into consideration and make sure to always cancel the interval at the
     * appropriate moment.  See the example below for more details on how and when to do this.
     * </div>
     *
     * @param {function()} fn A function that should be called repeatedly. If no additional arguments
     *   are passed (see below), the function is called with the current iteration count.
     * @param {number} delay Number of milliseconds between each function call.
     * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
     *   indefinitely.
     * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
     *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
     * @param {...*=} Pass additional parameters to the executed function.
     * @returns {promise} A promise which will be notified on each iteration. It will resolve once all iterations of the interval complete.

/**
 * @ngdoc service
 * @name $log
 * @requires $window
 *
 * @description
 * Simple service for logging. Default implementation safely writes the message
 * into the browser's console (if present).
 *
 * The main purpose of this service is to simplify debugging and troubleshooting.
 *
 * To reveal the location of the calls to `$log` in the JavaScript console,
 * you can "blackbox" the AngularJS source in your browser:
 *
 * [Mozilla description of blackboxing](https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Black_box_a_source).
 * [Chrome description of blackboxing](https://developer.chrome.com/devtools/docs/blackboxing).
 *
 * Note: Not all browsers support blackboxing.
 *
 * The default is to log `debug` messages. You can use
 * {@link ng.$logProvider ng.$logProvider#debugEnabled} to change this.
 *
 * @example
   <example module="logExample" name="log-service">
     <file name="script.js">
       angular.module('logExample', [])
         .controller('LogController', ['$scope', '$log', function($scope, $log) {
           $scope.$log = $log;
           $scope.message = 'Hello World!';
         }]);
     </file>
     <file name="index.html">
       <div ng-controller="LogController">
         <p>Reload this page with open console, enter text and hit the log button...</p>
         <label>Message:
         <input type="text" ng-model="message" /></label>
         <button ng-click="$log.log(message)">log</button>
         <button ng-click="$log.warn(message)">warn</button>
         <button ng-click="$log.info(message)">info</button>
         <button ng-click="$log.error(message)">error</button>
         <button ng-click="$log.debug(message)">debug</button>

//
// As an example, consider the following AngularJS expression:
//
//   {}.toString.constructor('alert("evil JS code")')
//
// It is important to realize that if you create an expression from a string that contains user provided
// content then it is possible that your application contains a security vulnerability to an XSS style attack.

  //
  // TypeError: Cannot convert object to primitive value
  //
  // For performance reasons, we don't catch this error here and allow it to propagate up the call

/**
 * @ngdoc service
 * @name $q
 * @requires $rootScope
 *
 * @description
 * A service that helps you run functions asynchronously, and use their return values (or exceptions)
 * when they are done processing.
 *
 * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
 * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
 *
 * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
 * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
 *
 * ## $q constructor
 *
 * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
 * function as the first argument. This is similar to the native Promise implementation from ES6,
 * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
 *
 * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
 * available yet.
 *
 * It can be used like so:
 *
 * ```js
 *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
 *   // are available in the current lexical scope (they could have been injected or passed in).
 *
 *   function asyncGreet(name) {
 *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
 *     return $q(function(resolve, reject) {
 *       setTimeout(function() {
 *         if (okToGreet(name)) {
 *           resolve('Hello, ' + name + '!');
 *         } else {
 *           reject('Greeting ' + name + ' is not allowed.');
 *         }
 *       }, 1000);
 *     });
 *   }
 *
 *   var promise = asyncGreet('Robin Hood');
 *   promise.then(function(greeting) {
 *     alert('Success: ' + greeting);
 *   }, function(reason) {
 *     alert('Failed: ' + reason);
 *   });
 * ```
 *
 * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
 *
 * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
 *
 * However, the more traditional CommonJS-style usage is still available, and documented below.
 *
 * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
 * interface for interacting with an object that represents the result of an action that is
 * performed asynchronously, and may or may not be finished at any given point in time.
 *
 * From the perspective of dealing with error handling, deferred and promise APIs are to
 * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
 *
 * ```js
 *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
 *   // are available in the current lexical scope (they could have been injected or passed in).
 *
 *   function asyncGreet(name) {
 *     var deferred = $q.defer();
 *
 *     setTimeout(function() {
 *       deferred.notify('About to greet ' + name + '.');
 *
 *       if (okToGreet(name)) {
 *         deferred.resolve('Hello, ' + name + '!');
 *       } else {
 *         deferred.reject('Greeting ' + name + ' is not allowed.');
 *       }
 *     }, 1000);
 *
 *     return deferred.promise;
 *   }
 *
 *   var promise = asyncGreet('Robin Hood');
 *   promise.then(function(greeting) {
 *     alert('Success: ' + greeting);
 *   }, function(reason) {
 *     alert('Failed: ' + reason);
 *   }, function(update) {
 *     alert('Got notification: ' + update);
 *   });
 * ```
 *
 * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
 * comes in the way of guarantees that promise and deferred APIs make, see
 * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
 *
 * Additionally the promise api allows for composition that is very hard to do with the
 * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
 * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
 * section on serial or parallel joining of promises.
 *
 * ## The Deferred API
 *
 * A new instance of deferred is constructed by calling `$q.defer()`.
 *
 * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
 * that can be used for signaling the successful or unsuccessful completion, as well as the status
 * of the task.
 *
 * **Methods**
 *
 * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
 *   constructed via `$q.reject`, the promise will be rejected instead.
 * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
 *   resolving it with a rejection constructed via `$q.reject`.
 * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
 *   multiple times before the promise is either resolved or rejected.
 *
 * **Properties**
 *
 * - promise – `{Promise}` – promise object associated with this deferred.
 *
 *
 * ## The Promise API
 *
 * A new promise instance is created when a deferred instance is created and can be retrieved by
 * calling `deferred.promise`.
 *
 * The purpose of the promise object is to allow for interested parties to get access to the result
 * of the deferred task when it completes.
 *
 * **Methods**
 *
 * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
 *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
 *   as soon as the result is available. The callbacks are called with a single argument: the result
 *   or rejection reason. Additionally, the notify callback may be called zero or more times to
 *   provide a progress indication, before the promise is resolved or rejected.
 *
 *   This method *returns a new promise* which is resolved or rejected via the return value of the
 *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
 *   with the value which is resolved in that promise using
 *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
 *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
 *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
 *   arguments are optional.
 *
 * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
 *
 * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
 *   but to do so without modifying the final value. This is useful to release resources or do some
 *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
 *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
 *   more information.
 *
 * ## Chaining promises
 *
 * Because calling the `then` method of a promise returns a new derived promise, it is easily
 * possible to create a chain of promises:
 *
 * ```js
 *   promiseB = promiseA.then(function(result) {
 *     return result + 1;
 *   });
 *
 *   // promiseB will be resolved immediately after promiseA is resolved and its value
 *   // will be the result of promiseA incremented by 1
 * ```
 *
 * It is possible to create chains of any length and since a promise can be resolved with another
 * promise (which will defer its resolution further), it is possible to pause/defer resolution of
 * the promises at any point in the chain. This makes it possible to implement powerful APIs like
 * $http's response interceptors.
 *
 *
 * ## Differences between Kris Kowal's Q and $q
 *
 *  There are two main differences:
 *
 * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
 *   mechanism in AngularJS, which means faster propagation of resolution or rejection into your
 *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
 * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
 *   all the important functionality needed for common async tasks.
 *
 * ## Testing
 *
 *  ```js
 *    it('should simulate promise', inject(function($q, $rootScope) {
 *      var deferred = $q.defer();
 *      var promise = deferred.promise;
 *      var resolvedValue;
 *
 *      promise.then(function(value) { resolvedValue = value; });
 *      expect(resolvedValue).toBeUndefined();
 *
 *      // Simulate resolving of promise
 *      deferred.resolve(123);
 *      // Note that the 'then' function does not get called synchronously.
 *      // This is because we want the promise API to always be async, whether or not
 *      // it got called synchronously or asynchronously.
 *      expect(resolvedValue).toBeUndefined();
 *
 *      // Propagate promise resolution to 'then' functions using $apply().
 *      $rootScope.$apply();
 *      expect(resolvedValue).toEqual(123);
 *    }));
 *  ```
 *
 * @param {function(function, function)} resolver Function which is responsible for resolving or
 *   rejecting the newly created promise. The first parameter is a function which resolves the
 *   promise, the second parameter is a function which rejects the promise.
 *
 * @returns {Promise} The newly created promise.

/**
 * DESIGN NOTES
 *
 * The design decisions behind the scope are heavily favored for speed and memory consumption.
 *
 * The typical use of scope is to watch the expressions, which most of the time return the same
 * value as last time so we optimize the operation.
 *
 * Closures construction is expensive in terms of speed as well as memory:
 *   - No closures, instead use prototypical inheritance for API
 *   - Internal state needs to be stored on scope directly, which means that private state is
 *     exposed as $$____ properties
 *
 * Loop operations are optimized by using while(count--) { ... }
 *   - This means that in order to keep the same order of execution as addition we have to add
 *     items to the array at the beginning (unshift) instead of at the end (push)
 *
 * Child scopes are created and removed often
 *   - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
 *
 * There are fewer watches than observers. This is why you don't want the observer to be implemented
 * in the same way as watch. Watch requires return of the initialization function which is expensive
 * to construct.

     * @name $rootScope.Scope
     *
     * @description
     * A root scope can be retrieved using the {@link ng.$rootScope $rootScope} key from the
     * {@link auto.$injector $injector}. Child scopes are created using the
     * {@link ng.$rootScope.Scope#$new $new()} method. (Most scopes are created automatically when
     * compiled HTML template is executed.) See also the {@link guide/scope Scopes guide} for
     * an in-depth introduction and usage examples.
     *
     *
     * ## Inheritance
     * A scope can inherit from a parent scope, as in this example:
     * ```js
         var parent = $rootScope;
         var child = parent.$new();

         parent.salutation = "Hello";
         expect(child.salutation).toEqual('Hello');

         child.salutation = "Welcome";
         expect(child.salutation).toEqual('Welcome');
         expect(parent.salutation).toEqual('Hello');
     * ```
     *
     * When interacting with `Scope` in tests, additional helper methods are available on the
     * instances of `Scope` type. See {@link ngMock.$rootScope.Scope ngMock Scope} for additional
     * details.
     *
     *
     * @param {Object.<string, function()>=} providers Map of service factory which need to be
     *                                       provided for the current scope. Defaults to {@link ng}.
     * @param {Object.<string, *>=} instanceCache Provides pre-instantiated services which should
     *                              append/override services provided by `providers`. This is handy
     *                              when unit-testing and having the need to override a default
     *                              service.
     * @returns {Object} Newly created scope.

       * @kind function
       *
       * @description
       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
       *
       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
       *   its value when executed multiple times with the same input because it may be executed multiple
       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
       * - The `listener` is called only when the value from the current `watchExpression` and the
       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
       *   see below). Inequality is determined according to reference inequality,
       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
       *    via the `!==` Javascript operator, unless `objectEquality == true`
       *   (see next point)
       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
       *   according to the {@link angular.equals} function. To save the value of the object for
       *   later comparison, the {@link angular.copy} function is used. This therefore means that
       *   watching complex objects will have adverse memory and performance implications.
       * - This should not be used to watch for changes in objects that are (or contain)
       *   [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
       *   iteration limit is 10 to prevent an infinite loop deadlock.
       *
       *
       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
       * you can register a `watchExpression` function with no `listener`. (Be prepared for
       * multiple calls to your `watchExpression` because it will execute multiple times in a
       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
       *
       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
       * watcher. In rare cases, this is undesirable because the listener is called when the result
       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
       * listener was called due to initialization.
       *
       *
       *
       * @example
       * ```js
           // let's assume that scope was dependency injected as the $rootScope
           var scope = $rootScope;
           scope.name = 'misko';
           scope.counter = 0;

           expect(scope.counter).toEqual(0);
           scope.$watch('name', function(newValue, oldValue) {
             scope.counter = scope.counter + 1;
           });
           expect(scope.counter).toEqual(0);

           scope.$digest();
           // the listener is always called during the first $digest loop after it was registered
           expect(scope.counter).toEqual(1);

           scope.$digest();
           // but now it will not be called unless the value changes
           expect(scope.counter).toEqual(1);

             // This is the change listener, called when the value returned from the above function changes
             function(newValue, oldValue) {
               if ( newValue !== oldValue ) {
                 // Only increment the counter if the value changed
                 scope.foodCounter = scope.foodCounter + 1;
               }
             }

       * @kind function
       *
       * @description
       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
       * until no more listeners are firing. This means that it is possible to get into an infinite
       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
       * iterations exceeds 10.
       *
       * Usually, you don't call `$digest()` directly in
       * {@link ng.directive:ngController controllers} or in
       * {@link ng.$compileProvider#directive directives}.
       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
       *
       * If you want to be notified whenever `$digest()` is called,
       * you can register a `watchExpression` function with
       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
       *
       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
       *
       * @example
       * ```js
           var scope = ...;
           scope.name = 'misko';
           scope.counter = 0;

           expect(scope.counter).toEqual(0);

       * @description
       * Suspend watchers of this scope subtree so that they will not be invoked during digest.
       *
       * This can be used to optimize your application when you know that running those watchers
       * is redundant.
       *
       * **Warning**
       *
       * Suspending scopes from the digest cycle can have unwanted and difficult to debug results.
       * Only use this approach if you are confident that you know what you are doing and have
       * ample tests to ensure that bindings get updated as you expect.
       *
       * Some of the things to consider are:
       *
       * * Any external event on a directive/component will not trigger a digest while the hosting
       *   scope is suspended - even if the event handler calls `$apply()` or `$rootScope.$digest()`.
       * * Transcluded content exists on a scope that inherits from outside a directive but exists
       *   as a child of the directive's containing scope. If the containing scope is suspended the
       *   transcluded scope will also be suspended, even if the scope from which the transcluded
       *   scope inherits is not suspended.
       * * Multiple directives trying to manage the suspended status of a scope can confuse each other:
       *    * A call to `$suspend()` on an already suspended scope is a no-op.
       *    * A call to `$resume()` on a non-suspended scope is a no-op.
       *    * If two directives suspend a scope, then one of them resumes the scope, the scope will no
       *      longer be suspended. This could result in the other directive believing a scope to be
       *      suspended when it is not.
       * * If a parent scope is suspended then all its descendants will be also excluded from future
       *   digests whether or not they have been suspended themselves. Note that this also applies to
       *   isolate child scopes.
       * * Calling `$digest()` directly on a descendant of a suspended scope will still run the watchers
       *   for that scope and its descendants. When digesting we only check whether the current scope is
       *   locally suspended, rather than checking whether it has a suspended ancestor.
       * * Calling `$resume()` on a scope that has a suspended ancestor will not cause the scope to be
       *   included in future digests until all its ancestors have been resumed.
       * * Resolved promises, e.g. from explicit `$q` deferreds and `$http` calls, trigger `$apply()`
       *   against the `$rootScope` and so will still trigger a global digest even if the promise was
       *   initiated by a component that lives on a suspended scope.

 *
 * @description
 *
 * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
 * Contextual Escaping (SCE)} services to AngularJS.
 *
 * For an overview of this service and the functionnality it provides in AngularJS, see the main
 * page for {@link ng.$sce SCE}. The current page is targeted for developers who need to alter how
 * SCE works in their application, which shouldn't be needed in most cases.
 *
 * <div class="alert alert-danger">
 * AngularJS strongly relies on contextual escaping for the security of bindings: disabling or
 * modifying this might cause cross site scripting (XSS) vulnerabilities. For libraries owners,
 * changes to this service will also influence users, so be extra careful and document your changes.
 * </div>
 *
 * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
 * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
 * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
 * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
 * work because `$sce` delegates to `$sceDelegate` for these operations.
 *
 * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
 *
 * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
 * can override it completely to change the behavior of `$sce`, the common case would
 * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
 * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
 * templates.  Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
 * $sceDelegateProvider.resourceUrlWhitelist} and {@link
 * ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}

 * @this
 *
 * @description
 *
 * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
 * $sceDelegate service}, used as a delegate for {@link ng.$sce Strict Contextual Escaping (SCE)}.
 *
 * The `$sceDelegateProvider` allows one to get/set the whitelists and blacklists used to ensure
 * that the URLs used for sourcing AngularJS templates and other script-running URLs are safe (all
 * places that use the `$sce.RESOURCE_URL` context). See
 * {@link ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist}
 * and
 * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist},
 *
 * For the general details about this service in AngularJS, read the main page for {@link ng.$sce
 * Strict Contextual Escaping (SCE)}.
 *
 * **Example**:  Consider the following case. <a name="example"></a>
 *
 * - your app is hosted at url `http://myapp.example.com/`
 * - but some of your templates are hosted on other domains you control such as
 *   `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
 * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
 *
 * Here is what a secure configuration for this scenario might look like:
 *
 * ```
 *  angular.module('myApp', []).config(function($sceDelegateProvider) {
 *    $sceDelegateProvider.resourceUrlWhitelist([
 *      // Allow same origin resource loads.
 *      'self',
 *      // Allow loading from our assets domain.  Notice the difference between * and **.
 *      'http://srv*.assets.example.com/**'
 *    ]);
 *
 *    // The blacklist overrides the whitelist so the open redirect here is blocked.
 *    $sceDelegateProvider.resourceUrlBlacklist([
 *      'http://myapp.example.com/clickThru**'
 *    ]);
 *  });
 * ```
 * Note that an empty whitelist will block every resource URL from being loaded, and will require
 * you to manually mark each one as trusted with `$sce.trustAsResourceUrl`. However, templates
 * requested by {@link ng.$templateRequest $templateRequest} that are present in
 * {@link ng.$templateCache $templateCache} will not go through this check. If you have a mechanism
 * to populate your templates in that cache at config time, then it is a good idea to remove 'self'
 * from that whitelist. This helps to mitigate the security impact of certain types of issues, like
 * for instance attacker-controlled `ng-includes`.

/**
 * @ngdoc service
 * @name $sce
 * @kind function
 *
 * @description
 *
 * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
 *
 * ## Strict Contextual Escaping
 *
 * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
 * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
 * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
 *
 * ### Overview
 *
 * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
 * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
 * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
 * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
 * can be sanitized, but template URLs cannot, for instance.
 *
 * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
 * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
 * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
 * render the input as-is, you will need to mark it as trusted for that context before attempting
 * to bind it.
 *
 * As of version 1.2, AngularJS ships with SCE enabled by default.
 *
 * ### In practice
 *
 * Here's an example of a binding in a privileged context:
 *
 * ```
 * <input ng-model="userHtml" aria-label="User input">
 * <div ng-bind-html="userHtml"></div>
 * ```
 *
 * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
 * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
 * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
 * articles, etc. via bindings. (HTML is just one example of a context where rendering user
 * controlled input creates security vulnerabilities.)
 *
 * For the case of HTML, you might use a library, either on the client side, or on the server side,
 * to sanitize unsafe HTML before binding to the value and rendering it in the document.
 *
 * How would you ensure that every place that used these types of bindings was bound to a value that
 * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
 * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
 * properties/fields and forgot to update the binding to the sanitized value?
 *
 * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
 * any similar validation process, unless there's a good reason to trust the given value in this
 * context.  That trust is formalized with a function call. This means that as a developer, you
 * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
 * you just need to ensure the values you mark as trusted indeed are safe - because they were
 * received from your server, sanitized by your library, etc. You can organize your codebase to
 * help with this - perhaps allowing only the files in a specific directory to do this.
 * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
 * becomes a more manageable task.
 *
 * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
 * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
 * build the trusted versions of your values.
 *
 * ### How does it work?
 *
 * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
 * $sce.getTrusted(context, value)} rather than to the value directly.  Think of this function as
 * a way to enforce the required security context in your data sink. Directives use {@link
 * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
 * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
 * when binding without directives, AngularJS will understand the context of your bindings
 * automatically.
 *
 * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
 * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
 * simplified):
 *
 * ```
 * var ngBindHtmlDirective = ['$sce', function($sce) {
 *   return function(scope, element, attr) {
 *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
 *       element.html(value || '');
 *     });
 *   };
 * }];
 * ```
 *
 * ### Impact on loading templates
 *
 * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
 * `templateUrl`'s specified by {@link guide/directive directives}.
 *
 * By default, AngularJS only loads templates from the same domain and protocol as the application
 * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
 * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
 * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
 * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
 *
 * *Please note*:
 * The browser's
 * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
 * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
 * policy apply in addition to this and may further restrict whether the template is successfully
 * loaded.  This means that without the right CORS policy, loading templates from a different domain
 * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
 * browsers.
 *
 * ### This feels like too much overhead
 *
 * It's important to remember that SCE only applies to interpolation expressions.
 *
 * If your expressions are constant literals, they're automatically trusted and you don't need to
 * call `$sce.trustAs` on them (e.g.
 * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works (remember to include the
 * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available
 * when binding untrusted values to `$sce.HTML` context.
 * AngularJS provides an implementation in `angular-sanitize.js`, and if you
 * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
 * your application.
 *
 * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
 * templates in `ng-include` from your application's domain without having to even know about SCE.
 * It blocks loading templates from other domains or loading templates over http from an https
 * served document.  You can change these by setting your own custom {@link
 * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
 * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
 *
 * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
 * application that's secure and can be audited to verify that with much more ease than bolting
 * security onto an application later.

 * ### What trusted context types are supported?
 *
 * | Context             | Notes          |
 * |---------------------|----------------|
 * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
 * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
 * | `$sce.MEDIA_URL`    | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. |
 * | `$sce.URL`          | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.|
 * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required. <br><br> The {@link $sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider#resourceUrlWhitelist()} and {@link $sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider#resourceUrlBlacklist()} can be used to restrict trusted origins for `RESOURCE_URL` |
 * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
 *
 *
 * <div class="alert alert-warning">
 * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their
 * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}.
 *
 * **As of 1.7.0, this is no longer the case.**
 *
 * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL`
 * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate`
 * service evaluates the expressions.
 * </div>
 *
 * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs`
 * functions aren't useful yet. This might evolve.
 *
 * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
 *
 *  Each element in these arrays must be one of the following:
 *
 *  - **'self'**
 *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
 *      domain** as the application document using the **same protocol**.
 *  - **String** (except the special value `'self'`)
 *    - The string is matched against the full *normalized / absolute URL* of the resource
 *      being tested (substring matches are not good enough.)
 *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
 *      match themselves.
 *    - `*`: matches zero or more occurrences of any character other than one of the following 6
 *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
 *      in a whitelist.
 *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
 *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
 *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
 *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
 *      http://foo.example.com/templates/**).
 *  - **RegExp** (*see caveat below*)
 *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
 *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
 *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
 *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
 *      small number of cases.  A `.` character in the regex used when matching the scheme or a
 *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
 *      is highly recommended to use the string patterns and only fall back to regular expressions
 *      as a last resort.
 *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
 *      matched against the **entire** *normalized / absolute URL* of the resource being tested
 *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
 *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
 *    - If you are generating your JavaScript from some other templating engine (not
 *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
 *      remember to escape your regular expression (and be aware that you might need more than
 *      one level of escaping depending on your templating engine and the way you interpolated
 *      the value.)  Do make use of your platform's escaping mechanism as it might be good
 *      enough before coding your own.  E.g. Ruby has
 *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
 *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
 *      Javascript lacks a similar built in function for escaping.  Take a look at Google
 *      Closure library's [goog.string.regExpEscape(s)](
 *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
 *
 * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

 *
 * ## Can I disable SCE completely?
 *
 * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
 * for little coding overhead.  It will be much harder to take an SCE disabled application and
 * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
 * for cases where you have a lot of existing code that was written before SCE was introduced and
 * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
 * you are writing a library, you will cause security bugs applications using it.
 *
 * That said, here's how you can completely disable SCE:
 *
 * ```
 * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
 *   // Completely disable SCE.  For demonstration purposes only!
 *   // Do not use in new projects or libraries.
 *   $sceProvider.enabled(false);
 * });
 * ```
 *

  /* Design notes on the default implementation for SCE.
   *
   * The API contract for the SCE delegate
   * -------------------------------------
   * The SCE delegate object must provide the following 3 methods:
   *
   * - trustAs(contextEnum, value)
   *     This method is used to tell the SCE service that the provided value is OK to use in the
   *     contexts specified by contextEnum.  It must return an object that will be accepted by
   *     getTrusted() for a compatible contextEnum and return this value.
   *
   * - valueOf(value)
   *     For values that were not produced by trustAs(), return them as is.  For values that were
   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
   *     such a value.
   *
   * - getTrusted(contextEnum, value)
   *     This function should return the value that is safe to use in the context specified by
   *     contextEnum or throw and exception otherwise.
   *
   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
   * instance, an implementation could maintain a registry of all trusted objects by context.  In
   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
   * return the same object passed in if it was found in the registry under a compatible context or
   * throw an exception otherwise.  An implementation might only wrap values some of the time based
   * on some criteria.  getTrusted() might return a value and not throw an exception for special
   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
   *
   *
   * A note on the inheritance model for SCE contexts
   * ------------------------------------------------
   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
   * is purely an implementation details.
   *
   * The contract is simply this:
   *
   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
   *     will also succeed.
   *
   * Inheritance happens to capture this in a natural way. In some future, we may not use
   * inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
   * be aware of this detail.

 *
 * Implementation Notes for non-IE browsers
 * ----------------------------------------
 * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
 * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
 * URL will be resolved into an absolute URL in the context of the application document.
 * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
 * properties are all populated to reflect the normalized URL.  This approach has wide
 * compatibility - Safari 1+, Mozilla 1+ etc.  See
 * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
 *
 * Implementation Notes for IE
 * ---------------------------
 * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
 * browsers.  However, the parsed components will not be set if the URL assigned did not specify
 * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
 * work around that by performing the parsing in a 2nd step by taking a previously normalized
 * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
 * properties such as protocol, hostname, port, etc.

 * <div class="alert alert-info">
 *   **Note**: If the array contains objects that reference themselves, filtering is not possible.
 * </div>
 * @param {string|Object|function()} expression The predicate to be used for selecting items from

 *
 *   Can be one of:
 *
 *   - `string`: The string is used for matching against the contents of the `array`. All strings or
 *     objects with string properties in `array` that match this string will be returned. This also
 *     applies to nested object properties.
 *     The predicate can be negated by prefixing the string with `!`.
 *
 *   - `Object`: A pattern object can be used to filter specific properties on objects contained
 *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
 *     which have property `name` containing "M" and property `phone` containing "1". A special
 *     property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
 *     against any property of the object or its nested object properties. That's equivalent to the

 *     overwritten, using the `anyPropertyKey` parameter.
 *     The predicate can be negated by prefixing the string with `!`.
 *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
 *     not containing "M".
 *
 *     Note that a named property will match properties on the same level only, while the special
 *     `$` property will match properties on the same level or deeper. E.g. an array item like
 *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
 *     **will** be matched by `{$: 'John'}`.
 *
 *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
 *     The function is called for each element of the array, with the element, its index, and
 *     the entire array itself as arguments.
 *
 *     The final result is an array of those elements that the predicate returned true for.
 *
 * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
 *     determining if values retrieved using `expression` (when it is not a function) should be
 *     considered a match based on the expected value (from the filter expression) and actual
 *     value (from the object in the array).
 *
 *   Can be one of:
 *
 *   - `function(actual, expected)`:
 *     The function will be given the object value and the predicate value to compare and
 *     should return true if both values should be considered equal.
 *
 *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
 *     This is essentially strict comparison of expected and actual.
 *
 *   - `false`: A short hand for a function which will look for a substring match in a case
 *     insensitive way. Primitive values are converted to strings. Objects are not compared against
 *     primitives, unless they have a custom `toString` method (e.g. `Date` objects).
 *
 *
 *   Defaults to `false`.
 *
 * @param {string} [anyPropertyKey] The special property name that matches against any property.
 *     By default `$`.

/**
 * @ngdoc filter
 * @name date
 * @kind function
 *
 * @description
 *   Formats `date` to a string based on the requested `format`.
 *
 *   `format` string can be composed of the following elements:
 *
 *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
 *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
 *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
 *   * `'MMMM'`: Month in year (January-December)
 *   * `'MMM'`: Month in year (Jan-Dec)
 *   * `'MM'`: Month in year, padded (01-12)
 *   * `'M'`: Month in year (1-12)
 *   * `'LLLL'`: Stand-alone month in year (January-December)
 *   * `'dd'`: Day in month, padded (01-31)
 *   * `'d'`: Day in month (1-31)
 *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
 *   * `'EEE'`: Day in Week, (Sun-Sat)
 *   * `'HH'`: Hour in day, padded (00-23)
 *   * `'H'`: Hour in day (0-23)
 *   * `'hh'`: Hour in AM/PM, padded (01-12)
 *   * `'h'`: Hour in AM/PM, (1-12)
 *   * `'mm'`: Minute in hour, padded (00-59)
 *   * `'m'`: Minute in hour (0-59)
 *   * `'ss'`: Second in minute, padded (00-59)
 *   * `'s'`: Second in minute (0-59)
 *   * `'sss'`: Millisecond in second, padded (000-999)
 *   * `'a'`: AM/PM marker
 *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
 *   * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
 *   * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
 *   * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
 *   * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
 *
 *   `format` string can also be one of the following predefined
 *   {@link guide/i18n localizable formats}:
 *
 *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
 *     (e.g. Sep 3, 2010 12:05:08 PM)
 *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 PM)
 *   * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US  locale
 *     (e.g. Friday, September 3, 2010)
 *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
 *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
 *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
 *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
 *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
 *
 *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
 *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
 *   (e.g. `"h 'o''clock'"`).
 *
 *   Any other characters in the `format` string will be output as-is.
 *
 * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
 *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
 *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
 *    specified in the string input, the time is considered to be in the local timezone.
 * @param {string=} format Formatting rules (see Description). If not specified,
 *    `mediumDate` is used.
 * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
 *    continental US time zone abbreviations, but for general use, use a time zone offset, for
 *    example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
 *    If not specified, the timezone of the browser will be used.
 * @returns {string} Formatted string or the input if input is not recognized as date/millis.

 * the value and sign (positive or negative) of `limit`. Other array-like objects are also supported
 * (e.g. array subclasses, NodeLists, jqLite/jQuery collections etc). If a number is used as input,
 * it is converted to a string.

 * @param {Array|ArrayLike|string|number} input - Array/array-like, string or number to be limited.
 * @param {string|number} limit - The length of the returned array or string. If the `limit` number
 *     is positive, `limit` number of items from the beginning of the source array/string are copied.
 *     If the number is negative, `limit` number  of items from the end of the source array/string
 *     are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined,
 *     the input will be returned unchanged.

/**
 * @ngdoc filter
 * @name orderBy
 * @kind function
 *
 * @description
 * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
 * function based on the values computed using the `expression` predicate.
 *
 * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
 * `[{id: 'bar'}, {id: 'foo'}]`.
 *
 * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
 * String, etc).
 *
 * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
 * for the preceding one. The `expression` is evaluated against each item and the output is used
 * for comparing with other items.
 *
 * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
 * ascending order.
 *
 * The comparison is done using the `comparator` function. If none is specified, a default, built-in
 * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
 * strings alphabetically).
 *
 * ### Under the hood
 *
 * Ordering the specified `collection` happens in two phases:
 *
 * 1. All items are passed through the predicate (or predicates), and the returned values are saved
 *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
 *    through a predicate that extracts the value of the `label` property, would be transformed to:
 *    ```
 *    {
 *      value: 'foo',
 *      type: 'string',
 *      index: ...
 *    }
 *    ```
 *    **Note:** `null` values use `'null'` as their type.
 * 2. The comparator function is used to sort the items, based on the derived values, types and
 *    indices.
 *
 * If you use a custom comparator, it will be called with pairs of objects of the form
 * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
 * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
 * second, or `1` otherwise.
 *
 * In order to ensure that the sorting will be deterministic across platforms, if none of the
 * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
 * dummy predicate that returns the item's index as `value`.
 * (If you are using a custom comparator, make sure it can handle this predicate as well.)
 *
 * If a custom comparator still can't distinguish between two items, then they will be sorted based
 * on their index using the built-in comparator.
 *
 * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
 * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
 * it to the comparator. The following rules govern the conversion:
 *
 * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
 *    used instead.<br />
 *    (If the object has a `valueOf()` method that returns another object, then the returned object
 *    will be used in subsequent steps.)
 * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
 *    returns a primitive, its return value will be used instead.<br />
 *    (If the object has a `toString()` method that returns another object, then the returned object
 *    will be used in subsequent steps.)
 * 3. No conversion; the object itself is used.
 *
 * ### The default comparator
 *
 * The default, built-in comparator should be sufficient for most usecases. In short, it compares
 * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
 * using their index in the original collection, sorts values of different types by type and puts
 * `undefined` and `null` values at the end of the sorted list.
 *
 * More specifically, it follows these steps to determine the relative order of items:
 *
 * 1. If the compared values are of different types:
 *    - If one of the values is undefined, consider it "greater than" the other.
 *    - Else if one of the values is null, consider it "greater than" the other.
 *    - Else compare the types themselves alphabetically.
 * 2. If both values are of type `string`, compare them alphabetically in a case- and
 *    locale-insensitive way.
 * 3. If both values are objects, compare their indices instead.
 * 4. Otherwise, return:
 *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
 *    - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
 *    -  `1`, otherwise.
 *
 * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
 *           saved as numbers and not strings.
 * **Note:** For the purpose of sorting, `null` and `undefined` are considered "greater than"
 *           any other value (with undefined "greater than" null). This effectively means that `null`
 *           and `undefined` values end up at the end of a list sorted in ascending order.
 * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects.
 *
 * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
 * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
 *    predicates) to be used by the comparator to determine the order of elements.
 *
 *    Can be one of:
 *
 *    - `Function`: A getter function. This function will be called with each item as argument and
 *      the return value will be used for sorting.
 *    - `string`: An AngularJS expression. This expression will be evaluated against each item and the
 *      result will be used for sorting. For example, use `'label'` to sort by a property called
 *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
 *      property.<br />
 *      (The result of a constant expression is interpreted as a property name to be used for
 *      comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
 *      property called `special name`.)<br />
 *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
 *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
 *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
 *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
 *      relative order of two items, the next predicate is used as a tie-breaker.
 *
 * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
 *
 * @param {boolean=} reverse - If `true`, reverse the sorting order.
 * @param {(Function)=} comparator - The comparator function used to determine the relative order of
 *    value pairs. If omitted, the built-in comparator will be used.
 *
 * @returns {Array} - The sorted array.
 *
 *
 * @example
 * ### Ordering a table with `ngRepeat`
 *
 * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
 * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
 * it defaults to the built-in comparator.

 * It is also possible to call the `orderBy` filter manually, by injecting `orderByFilter`, and

 * ### Using a custom comparator
 *
 * If you have very specific requirements about the way items are sorted, you can pass your own
 * comparator function. For example, you might need to compare some strings in a locale-sensitive
 * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
 * argument - passing `false` retains the default sorting order, i.e. ascending.)
 *

 */

 /**
 * @ngdoc directive
 * @name form
 * @restrict E
 *
 * @description
 * Directive that instantiates
 * {@link form.FormController FormController}.
 *
 * If the `name` attribute is specified, the form controller is published onto the current scope under
 * this name.
 *
 * ## Alias: {@link ng.directive:ngForm `ngForm`}
 *
 * In AngularJS, forms can be nested. This means that the outer form is valid when all of the child
 * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
 * AngularJS provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
 * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
 * of controls needs to be determined.
 *
 * ## CSS classes
 *  - `ng-valid` is set if the form is valid.
 *  - `ng-invalid` is set if the form is invalid.
 *  - `ng-pending` is set if the form is pending.
 *  - `ng-pristine` is set if the form is pristine.
 *  - `ng-dirty` is set if the form is dirty.
 *  - `ng-submitted` is set if the form was submitted.
 *
 * Keep in mind that ngAnimate can detect each of these classes when added and removed.
 *
 *
 * ## Submitting a form and preventing the default action
 *
 * Since the role of forms in client-side AngularJS applications is different than in classical
 * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
 * page reload that sends the data to the server. Instead some javascript logic should be triggered
 * to handle the form submission in an application-specific way.
 *
 * For this reason, AngularJS prevents the default action (form submission to the server) unless the
 * `<form>` element has an `action` attribute specified.
 *
 * You can use one of the following two ways to specify what javascript method should be called when
 * a form is submitted:
 *
 * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
 * - {@link ng.directive:ngClick ngClick} directive on the first
  *  button or input field of type submit (input[type=submit])
 *
 * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
 * or {@link ng.directive:ngClick ngClick} directives.
 * This is because of the following form submission rules in the HTML specification:
 *
 * - If a form has only one input field then hitting enter in this field triggers form submit
 * (`ngSubmit`)
 * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
 * doesn't trigger submit
 * - if a form has one or more input fields and one or more buttons or input[type=submit] then
 * hitting enter in any of the input fields will trigger the click handler on the *first* button or
 * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
 *
 * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
 * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
 * to have access to the updated model.
 *
 * @animations
 * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
 * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
 * other validations that are performed within the form. Animations in ngForm are similar to how
 * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
 * as JS animations.
 *
 * The following example shows a simple way to utilize CSS transitions to style a form element
 * that has been rendered as invalid after it has been validated:
 *
 * <pre>
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-form {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-form.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * </pre>
 *
 * @example
    <example name="ng-form" deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
      <file name="index.html">
       <script>
         angular.module('formExample', [])
           .controller('FormController', ['$scope', function($scope) {
             $scope.userType = 'guest';
           }]);
       </script>
       <style>
        .my-form {
          transition:all linear 0.5s;
          background: transparent;
        }
        .my-form.ng-invalid {
          background: red;
        }

  /**
   * @ngdoc input
   * @name input[text]
   *
   * @description
   * Standard HTML text input with AngularJS data binding, inherited by most of the `input` elements.
   *
   *
   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} required Adds `required` validation error key if the value is not entered.
   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
   *    `required` when you want to data-bind to the `required` attribute.
   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
   *    minlength.
   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
   *    any length.
   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
   *    that contains the regular expression body that will be converted to a regular expression
   *    as in the ngPattern directive.
   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
   *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
   *    If the expression evaluates to a RegExp object, then this is used directly.
   *    If the expression evaluates to a string, then it will be converted to a RegExp
   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
   *    `new RegExp('^abc$')`.<br />
   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
   *    start at the index of the last search's match, thus not taking the whole input value into
   *    account.
   * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
   *    interaction with the input element.
   * @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.
   *    This parameter is ignored for input[type=password] controls, which will never trim the
   *    input.

     * @description
     * Input with date validation and transformation. In browsers that do not yet support
     * the HTML5 date input, a text element will be used. In that case, text must be entered in a valid ISO-8601
     * date format (yyyy-MM-dd), for example: `2009-01-06`. Since many
     * modern browsers do not yet support this input type, it is important to provide cues to users on the
     * expected input format via a placeholder or label.
     *
     * The model must always be a Date object, otherwise AngularJS will throw an error.
     * Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
     *
     * The timezone to be used to read/write the `Date` instance in the model can be defined using
     * {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
     *
     * @param {string} ngModel Assignable AngularJS expression to data-bind to.
     * @param {string=} name Property name of the form under which the control is published.
     * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be a
     *   valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
     *   (e.g. `min="{{minDate | date:'yyyy-MM-dd'}}"`). Note that `min` will also add native HTML5
     *   constraint validation.
     * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must be
     *   a valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
     *   (e.g. `max="{{maxDate | date:'yyyy-MM-dd'}}"`). Note that `max` will also add native HTML5
     *   constraint validation.
     * @param {(date|string)=} ngMin Sets the `min` validation constraint to the Date / ISO date string
     *   the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.
     * @param {(date|string)=} ngMax Sets the `max` validation constraint to the Date / ISO date string
     *   the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.
     * @param {string=} required Sets `required` validation error key if the value is not entered.
     * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
     *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
     *    `required` when you want to data-bind to the `required` attribute.

    * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
    *   This must be a valid ISO datetime format (yyyy-MM-ddTHH:mm:ss). You can also use interpolation
    *   inside this attribute (e.g. `min="{{minDatetimeLocal | date:'yyyy-MM-ddTHH:mm:ss'}}"`).
    *   Note that `min` will also add native HTML5 constraint validation.
    * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
    *   This must be a valid ISO datetime format (yyyy-MM-ddTHH:mm:ss). You can also use interpolation

   * ### HTML5 constraint validation and `allowInvalid`
   *
   * In browsers that follow the
   * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
   * If a non-number is entered in the input, the browser will report the value as an empty string,
   * which means the view / model values in `ngModel` and subsequently the scope value
   * will also be an empty string.
   *
   * @knownIssue
   *
   * ### Large numbers and `step` validation
   *
   * The `step` validation will not work correctly for very large numbers (e.g. 9999999999) due to
   * Javascript's arithmetic limitations. If you need to handle large numbers, purpose-built
   * libraries (e.g. https://github.com/MikeMcl/big.js/), can be included into AngularJS by
   * {@link guide/forms#modifying-built-in-validators overwriting the validators}
   * for `number` and / or `step`, or by {@link guide/forms#custom-validation applying custom validators}
   * to an `input[text]` element. The source for `input[number]` type can be used as a starting
   * point for both implementations.
   *
   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
   *    Can be interpolated.
   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
   *    Can be interpolated.
   * @param {string=} ngMin Like `min`, sets the `min` validation error key if the value entered is less than `ngMin`,
   *    but does not trigger HTML5 native validation. Takes an expression.
   * @param {string=} ngMax Like `max`, sets the `max` validation error key if the value entered is greater than `ngMax`,
   *    but does not trigger HTML5 native validation. Takes an expression.
   * @param {string=} step Sets the `step` validation error key if the value entered does not fit the `step` constraint.
   *    Can be interpolated.
   * @param {string=} ngStep Like `step`, sets the `step` validation error key if the value entered does not fit the `ngStep` constraint,
   *    but does not trigger HTML5 native validation. Takes an expression.
   * @param {string=} required Sets `required` validation error key if the value is not entered.
   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
   *    `required` when you want to data-bind to the `required` attribute.
   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
   *    minlength.
   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
   *    any length.
   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
   *    that contains the regular expression body that will be converted to a regular expression
   *    as in the ngPattern directive.
   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
   *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
   *    If the expression evaluates to a RegExp object, then this is used directly.
   *    If the expression evaluates to a string, then it will be converted to a RegExp
   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
   *    `new RegExp('^abc$')`.<br />
   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
   *    start at the index of the last search's match, thus not taking the whole input value into
   *    account.

  /**
   * @ngdoc input
   * @name input[range]
   *
   * @description
   * Native range input with validation and transformation.
   *
   * The model for the range input must always be a `Number`.
   *
   * IE9 and other browsers that do not support the `range` type fall back
   * to a text input without any default values for `min`, `max` and `step`. Model binding,
   * validation and number parsing are nevertheless supported.
   *
   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
   * in a way that never allows the input to hold an invalid value. That means:
   * - any non-numerical value is set to `(max + min) / 2`.
   * - any numerical value that is less than the current min val, or greater than the current max val
   * is set to the min / max val respectively.
   * - additionally, the current `step` is respected, so the nearest value that satisfies a step
   * is used.
   *
   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
   * for more info.
   *
   * This has the following consequences for AngularJS:
   *
   * Since the element value should always reflect the current model value, a range input
   * will set the bound ngModel expression to the value that the browser has set for the
   * input element. For example, in the following input `<input type="range" ng-model="model.value">`,
   * if the application sets `model.value = null`, the browser will set the input to `'50'`.
   * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
   *
   * That means the model for range will immediately be set to `50` after `ngModel` has been
   * initialized. It also means a range input can never have the required error.
   *
   * This does not only affect changes to the model value, but also to the values of the `min`,
   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
   * the input value, AngularJS will also update the model value.
   *
   * Automatic value adjustment also means that a range input element can never have the `required`,
   * `min`, or `max` errors.
   *
   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
   * when the step value changes dynamically - they do not adjust the element value correctly, but
   * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
   * error on the input, and set the model to `undefined`.
   *
   * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.
   *
   * @param {string}  ngModel Assignable AngularJS expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
   *                  than `min`. Can be interpolated.
   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
   *                  Can be interpolated.
   * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step`
   *                  Can be interpolated.
   * @param {expression=} ngChange AngularJS expression to be executed when the ngModel value changes due
   *                      to user interaction with the input element.
   * @param {expression=} ngChecked If the expression is truthy, then the `checked` attribute will be set on the
   *                      element. **Note** : `ngChecked` should not be used alongside `ngModel`.
   *                      Checkout {@link ng.directive:ngChecked ngChecked} for usage.

 *
 * @param {string} ngModel Assignable AngularJS expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} required Sets `required` validation error key if the value is not entered.
 * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
 *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
 *    `required` when you want to data-bind to the `required` attribute.
 * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
 *    minlength.
 * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
 *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any
 *    length.
 * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
 *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
 *    If the expression evaluates to a RegExp object, then this is used directly.
 *    If the expression evaluates to a string, then it will be converted to a RegExp
 *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
 *    `new RegExp('^abc$')`.<br />
 *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
 *    start at the index of the last search's match, thus not taking the whole input value into
 *    account.
 * @param {string=} ngChange AngularJS expression to be executed when input changes due to user

 * @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.
 *
 * @knownIssue
 *
 * When specifying the `placeholder` attribute of `<textarea>`, Internet Explorer will temporarily
 * insert the placeholder value as the textarea's content. If the placeholder value contains
 * interpolation (`{{ ... }}`), an error will be logged in the console when AngularJS tries to update
 * the value of the by-then-removed text node. This doesn't affect the functionality of the
 * textarea, but can be undesirable.
 *
 * You can work around this Internet Explorer issue by using `ng-attr-placeholder` instead of
 * `placeholder` on textareas, whenever you need interpolation in the placeholder value. You can
 * find more details on `ngAttr` in the
 * [Interpolation](guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes) section of the
 * Developer Guide.

 * @description
 * The `ngBind` attribute tells AngularJS to replace the text content of the specified HTML element
 * with the value of a given expression, and to update the text content when the value of that
 * expression changes.
 *
 * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
 * `{{ expression }}` which is similar but less verbose.
 *
 * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
 * displayed by the browser in its raw state before AngularJS compiles it. Since `ngBind` is an
 * element attribute, it makes the bindings invisible to the user while the page is loading.
 *
 * An alternative solution to this problem would be using the

 * @description
 * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
 * an expression that represents all classes to be added.
 *
 * The directive operates in three different ways, depending on which of three types the expression
 * evaluates to:
 *
 * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
 * names.
 *
 * 2. If the expression evaluates to an object, then for each key-value pair of the
 * object with a truthy value the corresponding key is used as a class name.
 *
 * 3. If the expression evaluates to an array, each element of the array should either be a string as in
 * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
 * to give you more control over what CSS classes appear. See the code below for an example of this.
 *
 *
 * The directive won't add duplicate classes if a particular class was already set.
 *
 * When the expression changes, the previously added classes are removed and only then are the
 * new classes added.
 *
 * @knownIssue
 * You should not use {@link guide/interpolation interpolation} in the value of the `class`
 * attribute, when using the `ngClass` directive on the same element.
 * See {@link guide/interpolation#known-issues here} for more info.
 *
 * @animations
 * | Animation                        | Occurs                              |
 * |----------------------------------|-------------------------------------|
 * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |
 * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |
 * | {@link ng.$animate#setClass setClass} | just before classes are added and classes are removed from the element at the same time |
 *
 * ### ngClass and pre-existing CSS3 Transitions/Animations
   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
   to view the step by step details of {@link $animate#addClass $animate.addClass} and
   {@link $animate#removeClass $animate.removeClass}.
 *
 * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
 *   of the evaluation can be a string representing space delimited class
 *   names, an array, or a map of class names to boolean values. In the case of a map, the
 *   names of the properties whose values are truthy will be added as css classes to the
 *   element.

 *
 * @description
 * The `ngCloak` directive is used to prevent the AngularJS html template from being briefly
 * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
 * directive to avoid the undesirable flicker effect caused by the html template display.
 *
 * The directive can be applied to the `<body>` element, but the preferred usage is to apply
 * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
 * of the browser view.
 *
 * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
 * `angular.min.js`.
 * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
 *
 * ```css
 * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
 *   display: none !important;
 * }
 * ```
 *
 * When this css rule is loaded by the browser, all html elements (including their children) that
 * are tagged with the `ngCloak` directive are hidden. When AngularJS encounters this directive
 * during the compilation of the template it deletes the `ngCloak` element attribute, making
 * the compiled element visible.
 *
 * For the best result, the `angular.js` script must be loaded in the head section of the html
 * document; alternatively, the css rule above must be included in the external stylesheet of the
 * application.

/**
 * @ngdoc directive
 * @name ngController
 *
 * @description
 * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
 * supports the principles behind the Model-View-Controller design pattern.
 *
 * MVC components in angular:
 *
 * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
 *   are accessed through bindings.
 * * View — The template (HTML with data bindings) that is rendered into the View.
 * * Controller — The `ngController` directive specifies a Controller class; the class contains business
 *   logic behind the application to decorate the scope with functions and values
 *
 * Note that you can also attach controllers to the DOM by declaring it in a route definition
 * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
 * again using `ng-controller` in the template itself.  This will cause the controller to be attached
 * and executed twice.
 *
 * @element ANY
 * @scope
 * @priority 500
 * @param {expression} ngController Name of a constructor function registered with the current
 * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
 * that on the current scope evaluates to a constructor function.
 *
 * The controller instance can be published into a scope property by specifying
 * `ng-controller="as propertyName"`.
 *
 * @example
 * Here is a simple form for editing user contact information. Adding, removing, clearing, and
 * greeting are methods declared on the controller (see source tab). These methods can
 * easily be called from the AngularJS markup. Any changes to the data are automatically reflected
 * in the View without the need for a manual update.
 *
 * Two different declaration styles are included below:
 *
 * * one binds methods and properties directly onto the controller using `this`:
 * `ng-controller="SettingsController1 as settings"`
 * * one injects `$scope` into the controller:
 * `ng-controller="SettingsController2"`
 *
 * The second option is more common in the AngularJS community, and is generally used in boilerplates
 * and in this guide. However, there are advantages to binding properties directly to the controller
 * and avoiding scope.
 *
 * * Using `controller as` makes it obvious which controller you are accessing in the template when
 * multiple controllers apply to an element.
 * * If you are writing your controllers as classes you have easier access to the properties and
 * methods, which will appear on the scope, from inside the controller code.
 * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
 * inheritance masking primitives.
 *
 * This example demonstrates the `controller as` syntax.
 *
 * <example name="ngControllerAs" module="controllerAsExample">
 *   <file name="index.html">
 *    <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings">
 *      <label>Name: <input type="text" ng-model="settings.name"/></label>

/**
 * @ngdoc directive
 * @name ngCsp
 *
 * @restrict A
 * @element ANY
 * @description
 *
 * AngularJS has some features that can conflict with certain restrictions that are applied when using
 * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
 *
 * If you intend to implement CSP with these rules then you must tell AngularJS not to use these
 * features.
 *
 * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
 *
 *
 * The following default rules in CSP affect AngularJS:
 *
 * * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute
 * code from strings is forbidden. AngularJS makes use of this in the {@link $parse} service to
 * provide a 30% increase in the speed of evaluating AngularJS expressions. (This CSP rule can be
 * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would
 * weaken the protections offered by CSP.)
 *
 * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.
 * This prevents apps from injecting custom styles directly into the document. AngularJS makes use of
 * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these
 * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`
 * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but
 * it is generally not recommended as it would weaken the protections offered by CSP.)
 *
 * If you do not provide `ngCsp` then AngularJS tries to autodetect if CSP is blocking dynamic code
 * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically
 * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a
 * CSP error to be logged in the console:
 *
 * ```
 * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
 * script in the following Content Security Policy directive: "default-src 'self'". Note that
 * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
 * ```
 *
 * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
 * directive on an element of the HTML document that appears before the `<script>` tag that loads
 * the `angular.js` file.
 *
 * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
 *
 * You can specify which of the CSP related AngularJS features should be deactivated by providing
 * a value for the `ng-csp` attribute. The options are as follows:
 *
 * * no-inline-style: this stops AngularJS from injecting CSS styles into the DOM
 *
 * * no-unsafe-eval: this stops AngularJS from optimizing $parse with unsafe eval of strings
 *
 * You can use these values in the following combinations:
 *
 *
 * * No declaration means that AngularJS will assume that you can do inline styles, but it will do
 * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous
 * versions of AngularJS.
 *
 * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell AngularJS to deactivate both inline
 * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous
 * versions of AngularJS.
 *
 * * Specifying only `no-unsafe-eval` tells AngularJS that we must not use eval, but that we can
 * inject inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
 *
 * * Specifying only `no-inline-style` tells AngularJS that we must not inject styles, but that we can
 * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
 *
 * * Specifying both `no-unsafe-eval` and `no-inline-style` tells AngularJS that we must not inject
 * styles nor use eval, which is the same as an empty: ng-csp.
 * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
 *
 * @example
 *
 * This example shows how to apply the `ngCsp` directive to the `html` tag.
   ```html
     <!doctype html>
     <html ng-app ng-csp>
     ...
     ...
     </html>

/**
 * @ngdoc directive
 * @name ngIf
 * @restrict A
 * @multiElement
 *
 * @description
 * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
 * {expression}. If the expression assigned to `ngIf` evaluates to a false
 * value then the element is removed from the DOM, otherwise a clone of the
 * element is reinserted into the DOM.
 *
 * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
 * element in the DOM rather than changing its visibility via the `display` css property.  A common
 * case when this difference is significant is when using css selectors that rely on an element's
 * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
 *
 * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
 * is created when the element is restored.  The scope created within `ngIf` inherits from
 * its parent scope using
 * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
 * An important implication of this is if `ngModel` is used within `ngIf` to bind to
 * a javascript primitive defined in the parent scope. In this case any modifications made to the
 * variable within the child scope will override (hide) the value in the parent scope.
 *
 * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
 * is if an element's class attribute is directly modified after it's compiled, using something like
 * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
 * the added class will be lost because the original compiled state is used to regenerate the element.
 *
 * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
 * and `leave` effects.
 *
 * @animations
 * | Animation                        | Occurs                               |
 * |----------------------------------|-------------------------------------|
 * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
 * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |
 *
 * @element ANY
 * @scope
 * @priority 600
 * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
 *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
 *     element is added to the DOM tree.
 *
 * @example
  <example module="ngAnimate" deps="angular-animate.js" animations="true" name="ng-if">

 * The `ngInit` directive allows you to evaluate an expression in the

 *
 * <div class="alert alert-danger">
 * This directive can be abused to add unnecessary amounts of logic into your templates.
 * There are only a few appropriate uses of `ngInit`:
 * <ul>
 *   <li>aliasing special properties of {@link ng.directive:ngRepeat `ngRepeat`},
 *     as seen in the demo below.</li>
 *   <li>initializing data during development, or for examples, as seen throughout these docs.</li>
 *   <li>injecting data via server side scripting.</li>
 * </ul>
 *
 * Besides these few cases, you should use {@link guide/component Components} or
 * {@link guide/controller Controllers} rather than `ngInit` to initialize values on a scope.
 * </div>
 *
 * <div class="alert alert-warning">
 * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
 * sure you have parentheses to ensure correct operator precedence:
 * <pre class="prettyprint">
 * `<div ng-init="test1 = ($index | toString)"></div>`
 * </pre>

 * @param {string=} ngList optional delimiter that should be used to split the value.
 *
 * @description
 * Text input that converts between a delimited string and an array of strings. The default
 * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
 * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
 *
 * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
 * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
 *   list item is respected. This implies that the user of the directive is responsible for
 *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
 *   tab or newline character.
 * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
 *   when joining the list items back together) and whitespace around each list item is stripped
 *   before it is added to the model.

/**
 * @ngdoc type
 * @name ngModel.NgModelController
 * @property {*} $viewValue The actual value from the control's view. For `input` elements, this is a
 * String. See {@link ngModel.NgModelController#$setViewValue} for information about when the $viewValue
 * is set.
 *
 * @property {*} $modelValue The value in the model that the control is bound to.
 *
 * @property {Array.<Function>} $parsers Array of functions to execute, as a pipeline, whenever
 *  the control updates the ngModelController with a new {@link ngModel.NgModelController#$viewValue
    `$viewValue`} from the DOM, usually via user input.
    See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
    Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.

  The functions are called in array order, each passing
    its return value through to the next. The last return value is forwarded to the
    {@link ngModel.NgModelController#$validators `$validators`} collection.

  Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
    `$viewValue`}.

  Returning `undefined` from a parser means a parse error occurred. In that case,
    no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
    will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
    is set to `true`. The parse error is stored in `ngModel.$error.parse`.

  This simple example shows a parser that would convert text input value to lowercase:
 * ```js
 * function parse(value) {
 *   if (value) {
 *     return value.toLowerCase();
 *   }
 * }
 * ngModelController.$parsers.push(parse);
 * ```

 *
 * @property {Array.<Function>} $formatters Array of functions to execute, as a pipeline, whenever
    the bound ngModel expression changes programmatically. The `$formatters` are not called when the
    value of the control is changed by user interaction.

  Formatters are used to format / convert the {@link ngModel.NgModelController#$modelValue
    `$modelValue`} for display in the control.

  The functions are called in reverse array order, each passing the value through to the
    next. The last return value is used as the actual DOM value.

  This simple example shows a formatter that would convert the model value to uppercase:

 * ```js
 * function format(value) {
 *   if (value) {
 *     return value.toUpperCase();
 *   }
 * }
 * ngModel.$formatters.push(format);
 * ```
 *
 * @property {Object.<string, function>} $validators A collection of validators that are applied
 *      whenever the model value changes. The key value within the object refers to the name of the
 *      validator while the function refers to the validation operation. The validation operation is
 *      provided with the model value as an argument and must return a true or false value depending
 *      on the response of that validation.
 *
 * ```js
 * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
 *   var value = modelValue || viewValue;
 *   return /[0-9]+/.test(value) &&
 *          /[a-z]+/.test(value) &&
 *          /[A-Z]+/.test(value) &&
 *          /\W+/.test(value);
 * };
 * ```
 *
 * @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to
 *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
 *      is expected to return a promise when it is run during the model validation process. Once the promise
 *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
 *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
 *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
 *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
 *      will only run once all synchronous validators have passed.
 *
 * Please note that if $http is used then it is important that the server returns a success HTTP response code
 * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
 *
 * ```js
 * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
 *   var value = modelValue || viewValue;
 *
 *   // Lookup user by username
 *   return $http.get('/api/users/' + value).
 *      then(function resolved() {
 *        //username exists, this means validation fails
 *        return $q.reject('exists');
 *      }, function rejected() {
 *        //username does not exist, therefore this validation passes
 *        return true;
 *      });
 * };
 * ```
 *
 * @property {Array.<Function>} $viewChangeListeners Array of functions to execute whenever
 *     a change to {@link ngModel.NgModelController#$viewValue `$viewValue`} has caused a change
 *     to {@link ngModel.NgModelController#$modelValue `$modelValue`}.
 *     It is called with no arguments, and its return value is ignored.
 *     This can be used in place of additional $watches against the model value.
 *
 * @property {Object} $error An object hash with all failing validator ids as keys.
 * @property {Object} $pending An object hash with all pending validator ids as keys.
 *
 * @property {boolean} $untouched True if control has not lost focus yet.
 * @property {boolean} $touched True if control has lost focus.
 * @property {boolean} $pristine True if user has not interacted with the control yet.
 * @property {boolean} $dirty True if user has already interacted with the control.
 * @property {boolean} $valid True if there is no error.
 * @property {boolean} $invalid True if at least one error on the control.
 * @property {string} $name The name attribute of the control.
 *
 * @description
 *
 * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
 * The controller contains services for data-binding, validation, CSS updates, and value formatting
 * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
 * listening to DOM events.
 * Such DOM related logic should be provided by other directives which make use of
 * `NgModelController` for data-binding to control elements.
 * AngularJS provides this DOM logic for most {@link input `input`} elements.
 * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
 * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
 *
 * @example
 * ### Custom Control Example
 * This example shows how to use `NgModelController` with a custom control to achieve
 * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
 * collaborate together to achieve the desired result.
 *
 * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
 * contents be edited in place by the user.
 *
 * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
 * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
 * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
 * that content using the `$sce` service.
 *
 * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
    <file name="style.css">
      [contenteditable] {
        border: 1px solid black;
        background-color: white;
        min-height: 20px;
      }

      .ng-invalid {
        border: 1px solid red;
      }

    </file>
    <file name="script.js">
      angular.module('customControl', ['ngSanitize']).

   *
   * Since `ng-model` does not do a deep watch, `$render()` is only invoked if the values of
   * `$modelValue` and `$viewValue` are actually different from their previous values. If `$modelValue`

   * @description
   * Cancel an update and reset the input element's value to prevent an update to the `$modelValue`,
   * which may be caused by a pending debounced event or because the input is waiting for some
   * future event.
   *
   * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
   * depend on special events such as `blur`, there can be a period when the `$viewValue` is out of
   * sync with the ngModel's `$modelValue`.
   *
   * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update
   * and reset the input to the last committed view value.
   *
   * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
   * programmatically before these debounced/future events have resolved/occurred, because AngularJS's
   * dirty checking mechanism is not able to tell whether the model has actually changed or not.
   *
   * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
   * input which may have such events pending. This is important in order to make sure that the
   * input field will be updated with the new model value and any pending operations are cancelled.
   *

   * Update the view value.
   *
   * This method should be called when a control wants to change the view value; typically,
   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
   * directive calls it when the value of the input changes and {@link ng.directive:select select}
   * calls it when an option is selected.
   *
   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
   * value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
   * `$asyncValidators` are called and the value is applied to `$modelValue`.
   * Finally, the value is set to the **expression** specified in the `ng-model` attribute and
   * all the registered change listeners, in the `$viewChangeListeners` list are called.
   *
   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
   * and the `default` trigger is not listed, all those actions will remain pending until one of the
   * `updateOn` events is triggered on the DOM element.
   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
   * directive is used with a custom debounce for this particular event.
   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
   * is specified, once the timer runs out.
   *
   * When used with standard inputs, the view value will always be a string (which is in some cases
   * parsed into another type, such as a `Date` object for `input[date]`.)
   * However, custom controls might also pass objects to this method. In this case, we should make
   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
   * perform a deep watch of objects, it only looks for a change of identity. If you only change
   * the property of the object then ngModel will not realize that the object has changed and
   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
   * not change properties of the copy once it has been passed to `$setViewValue`.
   * Otherwise you may cause the model value on the scope to change incorrectly.
   *
   * <div class="alert alert-info">
   * In any case, the value passed to the method should always reflect the current value
   * of the control. For example, if you are calling `$setViewValue` for an input element,
   * you should pass the input DOM value. Otherwise, the control and the scope model become
   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
   * the control's DOM value in any way. If we want to change the control's DOM value
   * programmatically, we should update the `ngModel` scope expression. Its new value will be
   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
   * to update the DOM, and finally call `$validate` on it.

   * - the `$modelValue` is run through the {@link ngModel.NgModelController#$formatters $formatters}
   * and the result is set to the {@link ngModel.NgModelController#$viewValue $viewValue}
   * - the `ng-empty` or `ng-not-empty` class is set on the element
   * - if the `$viewValue` has changed:
   *   - {@link ngModel.NgModelController#$render $render} is called on the control
   *   - the {@link ngModel.NgModelController#$validators $validators} are run and
   *   the validation status is set.
   *
   * This method is called by ngModel internally when the bound scope value changes.
   * Application developers usually do not have to call this function themselves.
   *
   * This function can be used when the `$viewValue` or the rendered DOM value are not correctly
   * formatted and the `$modelValue` must be run through the `$formatters` again.
   *
   * @example
   * Consider a text input with an autocomplete list (for fruit), where the items are
   * objects with a name and an id.
   * A user enters `ap` and then selects `Apricot` from the list.
   * Based on this, the autocomplete widget will call `$setViewValue({name: 'Apricot', id: 443})`,
   * but the rendered value will still be `ap`.
   * The widget can then call `ctrl.$processModelValue()` to run the model -> view
   * pipeline again, which formats the object to the string `Apricot`,
   * then updates the `$viewValue`, and finally renders it in the DOM.
   *

/**
 * @ngdoc directive
 * @name ngModel
 * @restrict A
 * @priority 1
 * @param {expression} ngModel assignable {@link guide/expression Expression} to bind to.
 *
 * @description
 * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
 * property on the scope using {@link ngModel.NgModelController NgModelController},
 * which is created and exposed by this directive.
 *
 * `ngModel` is responsible for:
 *
 * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
 *   require.
 * - Providing validation behavior (i.e. required, number, email, url).
 * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
 * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
 *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
 * - Registering the control with its parent {@link ng.directive:form form}.
 *
 * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
 * current scope. If the property doesn't already exist on this scope, it will be created
 * implicitly and added to the scope.
 *
 * For best practices on using `ngModel`, see:
 *
 *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
 *
 * For basic examples, how to use `ngModel`, see:
 *
 *  - {@link ng.directive:input input}
 *    - {@link input[text] text}
 *    - {@link input[checkbox] checkbox}
 *    - {@link input[radio] radio}
 *    - {@link input[number] number}
 *    - {@link input[email] email}
 *    - {@link input[url] url}
 *    - {@link input[date] date}
 *    - {@link input[datetime-local] datetime-local}
 *    - {@link input[time] time}
 *    - {@link input[month] month}
 *    - {@link input[week] week}
 *  - {@link ng.directive:select select}
 *  - {@link ng.directive:textarea textarea}
 *
 * ## Complex Models (objects or collections)
 *
 * By default, `ngModel` watches the model by reference, not value. This is important to know when
 * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
 * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
 *
 * The model must be assigned an entirely new object or collection before a re-rendering will occur.
 *
 * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
 * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
 * if the select is given the `multiple` attribute.
 *
 * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
 * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
 * not trigger a re-rendering of the model.
 *
 * ## CSS classes
 * The following CSS classes are added and removed on the associated input/select/textarea element
 * depending on the validity of the model.
 *
 *  - `ng-valid`: the model is valid
 *  - `ng-invalid`: the model is invalid
 *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
 *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
 *  - `ng-pristine`: the control hasn't been interacted with yet
 *  - `ng-dirty`: the control has been interacted with
 *  - `ng-touched`: the control has been blurred
 *  - `ng-untouched`: the control hasn't been blurred
 *  - `ng-pending`: any `$asyncValidators` are unfulfilled
 *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
 *     by the {@link ngModel.NgModelController#$isEmpty} method
 *  - `ng-not-empty`: the view contains a non-empty value
 *
 * Keep in mind that ngAnimate can detect each of these classes when added and removed.
 *
 * @animations
 * Animations within models are triggered when any of the associated CSS classes are added and removed
 * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
 * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
 * The animations that are triggered within ngModel are similar to how they work in ngClass and
 * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
 *
 * The following example shows a simple way to utilize CSS transitions to style an input element
 * that has been rendered as invalid after it has been validated:
 *
 * <pre>
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-input {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-input.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * </pre>
 *
 * @example
 * ### Basic Usage
 * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample" name="ng-model">
     <file name="index.html">
       <script>
        angular.module('inputExample', [])
          .controller('ExampleController', ['$scope', function($scope) {
            $scope.val = '1';
          }]);
       </script>
       <style>
         .my-input {
           transition:all linear 0.5s;
           background: transparent;
         }
         .my-input.ng-invalid {
           color:white;
           background: red;
         }
       </style>
       <p id="inputDescription">
        Update input to see transitions when valid/invalid.
        Integer is a valid value.
       </p>
       <form name="testForm" ng-controller="ExampleController">
         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
                aria-describedby="inputDescription" />
       </form>
     </file>
 * </example>
 *
 * @example
 * ### Binding to a getter/setter
 *
 * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
 * function that returns a representation of the model when called with zero arguments, and sets
 * the internal state of a model when called with an argument. It's sometimes useful to use this
 * for models that have an internal representation that's different from what the model exposes
 * to the view.
 *
 * <div class="alert alert-success">
 * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more
 * frequently than other parts of your code.
 * </div>
 *
 * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
 * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
 * a `<form>`, which will enable this behavior for all `<input>`s within it. See
 * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
 *
 * The following example shows how to use `ngModel` with a getter/setter:
 *
 * @example
 * <example name="ngModel-getter-setter" module="getterSetterExample">
     <file name="index.html">
       <div ng-controller="ExampleController">
         <form name="userForm">
           <label>Name:
             <input type="text" name="userName"
                    ng-model="user.name"
                    ng-model-options="{ getterSetter: true }" />
           </label>
         </form>
         <pre>user.name = <span ng-bind="user.name()"></span></pre>
       </div>
     </file>
     <file name="app.js">
       angular.module('getterSetterExample', [])
         .controller('ExampleController', ['$scope', function($scope) {
           var _name = 'Brian';
           $scope.user = {
             name: function(newName) {
              // Note that newName can be undefined for two reasons:
              // 1. Because it is called as a getter and thus called with no arguments
              // 2. Because the property should actually be set to undefined. This happens e.g. if the
              //    input is invalid
              return arguments.length ? (_name = newName) : _name;
             }
           };
         }]);

/**
 * @ngdoc directive

 * @priority 10
 *
 * @description
 * This directive allows you to modify the behaviour of {@link ngModel} directives within your
 * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
 * directives will use the options of their nearest `ngModelOptions` ancestor.
 *
 * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
 * an AngularJS expression. This expression should evaluate to an object, whose properties contain
 * the settings. For example: `<div ng-model-options="{ debounce: 100 }"`.
 *
 * ## Inheriting Options
 *
 * You can specify that an `ngModelOptions` setting should be inherited from a parent `ngModelOptions`
 * directive by giving it the value of `"$inherit"`.
 * Then it will inherit that setting from the first `ngModelOptions` directive found by traversing up the
 * DOM tree. If there is no ancestor element containing an `ngModelOptions` directive then default settings
 * will be used.
 *
 * For example given the following fragment of HTML
 *
 *
 * ```html
 * <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
 *   <form ng-model-options="{ updateOn: 'blur', allowInvalid: '$inherit' }">
 *     <input ng-model-options="{ updateOn: 'default', allowInvalid: '$inherit' }" />
 *   </form>
 * </div>
 * ```
 *
 * the `input` element will have the following settings
 *
 * ```js
 * { allowInvalid: true, updateOn: 'default', debounce: 0 }
 * ```
 *
 * Notice that the `debounce` setting was not inherited and used the default value instead.
 *
 * You can specify that all undefined settings are automatically inherited from an ancestor by
 * including a property with key of `"*"` and value of `"$inherit"`.
 *
 * For example given the following fragment of HTML
 *
 *
 * ```html
 * <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
 *   <form ng-model-options="{ updateOn: 'blur', "*": '$inherit' }">
 *     <input ng-model-options="{ updateOn: 'default', "*": '$inherit' }" />
 *   </form>
 * </div>
 * ```
 *
 * the `input` element will have the following settings
 *
 * ```js
 * { allowInvalid: true, updateOn: 'default', debounce: 200 }
 * ```
 *
 * Notice that the `debounce` setting now inherits the value from the outer `<div>` element.
 *
 * If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
 * since you may inadvertently inherit a setting in the future that changes the behavior of your component.
 *
 *
 * ## Triggering and debouncing model updates
 *
 * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
 * trigger a model update and/or a debouncing delay so that the actual update only takes place when
 * a timer expires; this timer will be reset after another change takes place.
 *
 * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
 * be different from the value in the actual model. This means that if you update the model you
 * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
 * order to make sure it is synchronized with the model and that any debounced action is canceled.
 *
 * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
 * method is by making sure the input is placed inside a form that has a `name` attribute. This is
 * important because `form` controllers are published to the related scope under the name in their
 * `name` attribute.
 *
 * Any pending changes will take place immediately when an enclosing form is submitted via the
 * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
 * to have access to the updated model.
 *
 * ### Overriding immediate updates
 *
 * The following example shows how to override immediate updates. Changes on the inputs within the
 * form will update the model only when the control loses focus (blur event). If `escape` key is
 * pressed while the input field is focused, the value is reset to the value in the current model.
 *
 * <example name="ngModelOptions-directive-blur" module="optionsExample">
 *   <file name="index.html">
 *     <div ng-controller="ExampleController">
 *       <form name="userForm">
 *         <label>
 *           Name:
 *           <input type="text" name="userName"
 *                  ng-model="user.name"
 *                  ng-model-options="{ updateOn: 'blur' }"
 *                  ng-keyup="cancel($event)" />
 *         </label><br />
 *         <label>
 *           Other data:
 *           <input type="text" ng-model="user.data" />
 *         </label><br />
 *       </form>
 *       <pre>user.name = <span ng-bind="user.name"></span></pre>
 *     </div>
 *   </file>
 *   <file name="app.js">
 *     angular.module('optionsExample', [])
 *       .controller('ExampleController', ['$scope', function($scope) {
 *         $scope.user = { name: 'say', data: '' };
 *
 *         $scope.cancel = function(e) {
 *           if (e.keyCode === 27) {
 *             $scope.userForm.userName.$rollbackViewValue();
 *           }
 *         };
 *       }]);
 *   </file>
 *   <file name="protractor.js" type="protractor">
 *     var model = element(by.binding('user.name'));
 *     var input = element(by.model('user.name'));
 *     var other = element(by.model('user.data'));
 *
 *     it('should allow custom events', function() {
 *       input.sendKeys(' hello');
 *       input.click();
 *       expect(model.getText()).toEqual('say');
 *       other.click();
 *       expect(model.getText()).toEqual('say hello');
 *     });
 *
 *     it('should $rollbackViewValue when model changes', function() {
 *       input.sendKeys(' hello');
 *       expect(input.getAttribute('value')).toEqual('say hello');
 *       input.sendKeys(protractor.Key.ESCAPE);
 *       expect(input.getAttribute('value')).toEqual('say');
 *       other.click();
 *       expect(model.getText()).toEqual('say');
 *     });
 *   </file>
 * </example>
 *
 * ### Debouncing updates
 *
 * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change.
 * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.
 *
 * <example name="ngModelOptions-directive-debounce" module="optionsExample">
 *   <file name="index.html">
 *     <div ng-controller="ExampleController">
 *       <form name="userForm">
 *         Name:
 *         <input type="text" name="userName"
 *                ng-model="user.name"
 *                ng-model-options="{ debounce: 1000 }" />
 *         <button ng-click="userForm.userName.$rollbackViewValue(); user.name=''">Clear</button><br />
 *       </form>
 *       <pre>user.name = <span ng-bind="user.name"></span></pre>
 *     </div>
 *   </file>
 *   <file name="app.js">
 *     angular.module('optionsExample', [])
 *       .controller('ExampleController', ['$scope', function($scope) {
 *         $scope.user = { name: 'say' };
 *       }]);
 *   </file>
 * </example>
 *
 * ### Default events, extra triggers, and catch-all debounce values
 *
 * This example shows the relationship between "default" update events and
 * additional `updateOn` triggers.
 *
 * `default` events are those that are bound to the control, and when fired, update the `$viewValue`
 * via {@link ngModel.NgModelController#$setViewValue $setViewValue}. Every event that is not listed
 * in `updateOn` is considered a "default" event, since different control types have different
 * default events.
 *
 * The control in this example updates by "default", "click", and "blur", with different `debounce`
 * values. You can see that "click" doesn't have an individual `debounce` value -
 * therefore it uses the `*` debounce value.
 *
 * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue}
 * directly with a "custom" event. Since "custom" is not defined in the `updateOn` list,
 * it is considered a "default" event and will update the
 * control if "default" is defined in `updateOn`, and will receive the "default" debounce value.
 * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`.
 *
 * You can change the `updateOn` and `debounce` configuration to test different scenarios. This
 * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}.
 *
  <example name="ngModelOptions-advanced" module="optionsExample">
    <file name="index.html">
       <model-update-demo></model-update-demo>
    </file>
    <file name="app.js">

        .component('modelUpdateDemo', {
          templateUrl: 'template.html',
          controller: function() {
            this.name = 'Chinua';

              updateOn: 'default blur click',
              debounce: {
                default: 2000,
                blur: 0,
                '*': 1000
              }
            };

            this.updateEvents = function() {
              var eventList = this.options.updateOn.split(' ');
              eventList.push('*');
              var events = {};

              for (var i = 0; i < eventList.length; i++) {
                events[eventList[i]] = this.options.debounce[eventList[i]];
              }

                updateOn: Object.keys(this.events).join(' ').replace('*', ''),
                debounce: this.events
              });

              this.form.input.$overrideModelOptions(options);

 *
 * ## Model updates and validation
 *
 * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
 * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
 * the model will still be updated even if the value is invalid.
 *
 *
 * ## Connecting to the scope
 *
 * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
 * on the scope refers to a "getter/setter" function rather than the value itself.
 *
 * The following example shows how to bind to getter/setters:
 *
 * <example name="ngModelOptions-directive-getter-setter" module="getterSetterExample">
 *   <file name="index.html">
 *     <div ng-controller="ExampleController">
 *       <form name="userForm">
 *         <label>
 *           Name:
 *           <input type="text" name="userName"
 *                  ng-model="user.name"
 *                  ng-model-options="{ getterSetter: true }" />
 *         </label>
 *       </form>
 *       <pre>user.name = <span ng-bind="user.name()"></span></pre>
 *     </div>
 *   </file>
 *   <file name="app.js">
 *     angular.module('getterSetterExample', [])
 *       .controller('ExampleController', ['$scope', function($scope) {
 *         var _name = 'Brian';
 *         $scope.user = {
 *           name: function(newName) {
 *             return angular.isDefined(newName) ? (_name = newName) : _name;
 *           }
 *         };
 *       }]);
 *   </file>
 * </example>
 *
 *
 * ## Programmatically changing options
 *
 * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not
 * watched for changes. However, it is possible to override the options on a single
 * {@link ngModel.NgModelController} instance with
 * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.
 * See also the example for
 * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values
 * Default events, extra triggers, and catch-all debounce values}.
 *
 *
 * ## Specifying timezones
 *
 * You can specify the timezone that date/time input directives expect by providing its name in the
 * `timezone` property.
 *
 *
 * ## Formatting the value of `time` and `datetime-local`
 *
 * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value
 * that is displayed in the control. Note that browsers may apply their own formatting
 * in the user interface.
 *
   <example name="ngModelOptions-time-format" module="timeExample">
     <file name="index.html">
       <time-example></time-example>
     </file>
     <file name="script.js">
        angular.module('timeExample', [])
          .component('timeExample', {
            templateUrl: 'timeExample.html',
            controller: function() {
              this.time = new Date(1970, 0, 1, 14, 57, 0);

              this.options = {
                timeSecondsFormat: 'ss',
                timeStripZeroSeconds: true
              };

              this.optionChange = function() {
                this.timeForm.timeFormatted.$overrideModelOptions(this.options);
                this.time = new Date(this.time);
              };
            }
          });
     </file>
     <file name="timeExample.html">
       <form name="$ctrl.timeForm">
         <strong>Default</strong>:
         <input type="time" ng-model="$ctrl.time" step="any" /><br>
         <strong>With options</strong>:
         <input type="time" name="timeFormatted" ng-model="$ctrl.time" step="any" ng-model-options="$ctrl.options" />
         <br>

           ng-change="$ctrl.optionChange()">
         <br>
         <code>timeStripZeroSeconds</code>:
         <input

      </file>
 *  </example>
 *
 * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
 *   and its descendents.
 *
 * **General options**:
 *
 *   - `updateOn`: string specifying which event should the input be bound to. You can set several
 *     events using an space delimited list. There is a special event called `default` that
 *     matches the default events belonging to the control. These are the events that are bound to
 *     the control, and when fired, update the `$viewValue` via `$setViewValue`.
 *
 *     `ngModelOptions` considers every event that is not listed in `updateOn` a "default" event,
 *     since different control types use different default events.
 *
 *     See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates
 *     Triggering and debouncing model updates}.
 *
 *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
 *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
 *     custom value for each event. For example:
 *     ```
 *     ng-model-options="{
 *       updateOn: 'default blur',
 *       debounce: { 'default': 500, 'blur': 0 }
 *     }"
 *     ```
 *     You can use the `*` key to specify a debounce value that applies to all events that are not
 *     specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:
 *     ```
 *     ng-model-options="{
 *       updateOn: 'default blur mouseup',
 *       debounce: { 'default': 500, 'blur': 0, '*': 1000 }
 *     }"
 *     ```
 *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
 *     not validate correctly instead of the default behavior of setting the model to undefined.
 *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
 *     `ngModel` as getters/setters.
 *
 *
 *  **Input-type specific options**:
 *
 *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
 *     `<input type="date" />`, `<input type="time" />`, ... . It understands UTC/GMT and the
 *     continental US time zone abbreviations, but for general use, use a time zone offset, for
 *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
 *     If not specified, the timezone of the browser will be used.
 *     Note that changing the timezone will have no effect on the current date, and is only applied after
 *     the next input / model change.
 *
 *   - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and
 *     milliseconds. The option follows the format string of {@link date date filter}.
 *     By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds).
 *     The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both
 *     seconds and milliseconds.
 *     Note that browsers that support `time` and `datetime-local` require the hour and minutes
 *     part of the time string, and may show the value differently in the user interface.
 *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.
 *
 *   - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the
 *     seconds and milliseconds from the formatted value if they are zero. This option is applied
 *     after `timeSecondsFormat`.
 *     This option can be used to make the formatting consistent over different browsers, as some
 *     browsers with support for `time` will natively hide the milliseconds and
 *     seconds if they are zero, but others won't, and browsers that don't implement these input
 *     types will always show the full string.
 *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.

 * The `ngNonBindable` directive tells AngularJS not to compile or bind the contents of the current

 * and bindings but which should be ignored by AngularJS. This could be the case if you have a site
 * that displays snippets of code, for instance.
 *
 * @example
 * In this example there are two locations where a simple interpolation binding (`{{}}`) is present,
 * but the one wrapped in `ngNonBindable` is left alone.

/**
 * @ngdoc directive
 * @name ngOptions
 * @restrict A
 *
 * @description
 *
 * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
 * elements for the `<select>` element using the array or object obtained by evaluating the
 * `ngOptions` comprehension expression.
 *
 * In many cases, {@link ng.directive:ngRepeat ngRepeat} can be used on `<option>` elements instead of
 * `ngOptions` to achieve a similar result. However, `ngOptions` provides some benefits:
 * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
 * comprehension expression
 * - reduced memory consumption by not creating a new scope for each repeated instance
 * - increased render speed by creating the options in a documentFragment instead of individually
 *
 * When an item in the `<select>` menu is selected, the array element or object property
 * represented by the selected option will be bound to the model identified by the `ngModel`
 * directive.
 *
 * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
 * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
 * option. See example below for demonstration.
 *
 * ## Complex Models (objects or collections)
 *
 * By default, `ngModel` watches the model by reference, not value. This is important to know when
 * binding the select to a model that is an object or a collection.
 *
 * One issue occurs if you want to preselect an option. For example, if you set
 * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
 * because the objects are not identical. So by default, you should always reference the item in your collection
 * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
 *
 * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
 * of the item not by reference, but by the result of the `track by` expression. For example, if your
 * collection items have an id property, you would `track by item.id`.
 *
 * A different issue with objects or collections is that ngModel won't detect if an object property or
 * a collection item changes. For that reason, `ngOptions` additionally watches the model using
 * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
 * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
 * has not changed identity, but only a property on the object or an item in the collection changes.
 *
 * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
 * if the model is an array). This means that changing a property deeper than the first level inside the
 * object/collection will not trigger a re-rendering.
 *
 * ## `select` **`as`**
 *
 * Using `select` **`as`** will bind the result of the `select` expression to the model, but
 * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
 * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
 * is used, the result of that expression will be set as the value of the `option` and `select` elements.
 *
 *
 * ### `select` **`as`** and **`track by`**
 *
 * <div class="alert alert-warning">
 * Be careful when using `select` **`as`** and **`track by`** in the same expression.
 * </div>
 *
 * Given this array of items on the $scope:
 *
 * ```js
 * $scope.items = [{
 *   id: 1,
 *   label: 'aLabel',
 *   subItem: { name: 'aSubItem' }
 * }, {
 *   id: 2,
 *   label: 'bLabel',
 *   subItem: { name: 'bSubItem' }
 * }];
 * ```
 *
 * This will work:
 *
 * ```html
 * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
 * ```
 * ```js
 * $scope.selected = $scope.items[0];
 * ```
 *
 * but this will not work:
 *
 * ```html
 * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
 * ```
 * ```js
 * $scope.selected = $scope.items[0].subItem;
 * ```
 *
 * In both examples, the **`track by`** expression is applied successfully to each `item` in the
 * `items` array. Because the selected option has been set programmatically in the controller, the
 * **`track by`** expression is also applied to the `ngModel` value. In the first example, the
 * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
 * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
 * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
 * is not matched against any `<option>` and the `<select>` appears as having no selected value.
 *
 *
 * @param {string} ngModel Assignable AngularJS expression to data-bind to.
 * @param {comprehension_expression} ngOptions in one of the following forms:
 *
 *   * for array data sources:
 *     * `label` **`for`** `value` **`in`** `array`
 *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
 *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
 *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`
 *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
 *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
 *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
 *        (for including a filter with `track by`)
 *   * for object data sources:
 *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
 *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
 *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
 *     * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
 *     * `select` **`as`** `label` **`group by`** `group`
 *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
 *     * `select` **`as`** `label` **`disable when`** `disable`
 *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
 *
 * Where:
 *
 *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
 *   * `value`: local variable which will refer to each item in the `array` or each property value
 *      of `object` during iteration.
 *   * `key`: local variable which will refer to a property name in `object` during iteration.
 *   * `label`: The result of this expression will be the label for `<option>` element. The
 *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
 *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
 *      element. If not specified, `select` expression will default to `value`.
 *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
 *      DOM element.
 *   * `disable`: The result of this expression will be used to disable the rendered `<option>`
 *      element. Return `true` to disable.
 *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
 *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
 *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
 *      even when the options are recreated (e.g. reloaded from the server).
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} required The control is considered valid only if value is entered.
 * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
 *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
 *    `required` when you want to data-bind to the `required` attribute.
 * @param {string=} ngAttrSize sets the size of the select element dynamically. Uses the
 * {@link guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes ngAttr} directive.

/**
 * @ngdoc directive
 * @name ngPluralize
 * @restrict EA
 *
 * @description
 * `ngPluralize` is a directive that displays messages according to en-US localization rules.
 * These rules are bundled with angular.js, but can be overridden
 * (see {@link guide/i18n AngularJS i18n} dev guide). You configure ngPluralize directive
 * by specifying the mappings between
 * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
 * and the strings to be displayed.
 *
 * ## Plural categories and explicit number rules
 * There are two
 * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
 * in AngularJS's default en-US locale: "one" and "other".
 *
 * While a plural category may match many numbers (for example, in en-US locale, "other" can match
 * any number that is not 1), an explicit number rule can only match one number. For example, the
 * explicit number rule for "3" matches the number 3. There are examples of plural categories
 * and explicit number rules throughout the rest of this documentation.
 *
 * ## Configuring ngPluralize
 * You configure ngPluralize by providing 2 attributes: `count` and `when`.
 * You can also provide an optional attribute, `offset`.
 *
 * The value of the `count` attribute can be either a string or an {@link guide/expression
 * AngularJS expression}; these are evaluated on the current scope for its bound value.
 *
 * The `when` attribute specifies the mappings between plural categories and the actual
 * string to be displayed. The value of the attribute should be a JSON object.
 *
 * The following example shows how to configure ngPluralize:
 *
 * ```html
 * <ng-pluralize count="personCount"
                 when="{'0': 'Nobody is viewing.',
 *                      'one': '1 person is viewing.',
 *                      'other': '{} people are viewing.'}">
 * </ng-pluralize>
 *```
 *
 * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
 * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
 * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
 * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
 * show "a dozen people are viewing".
 *
 * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
 * into pluralized strings. In the previous example, AngularJS will replace `{}` with
 * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
 * for <span ng-non-bindable>{{numberExpression}}</span>.
 *
 * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
 * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
 *
 * ## Configuring ngPluralize with offset
 * The `offset` attribute allows further customization of pluralized text, which can result in
 * a better user experience. For example, instead of the message "4 people are viewing this document",
 * you might display "John, Kate and 2 others are viewing this document".
 * The offset attribute allows you to offset a number by any desired value.
 * Let's take a look at an example:
 *
 * ```html
 * <ng-pluralize count="personCount" offset=2
 *               when="{'0': 'Nobody is viewing.',
 *                      '1': '{{person1}} is viewing.',
 *                      '2': '{{person1}} and {{person2}} are viewing.',
 *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
 *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
 * </ng-pluralize>
 * ```
 *
 * Notice that we are still using two plural categories(one, other), but we added
 * three explicit number rules 0, 1 and 2.
 * When one person, perhaps John, views the document, "John is viewing" will be shown.
 * When three people view the document, no explicit number rule is found, so
 * an offset of 2 is taken off 3, and AngularJS uses 1 to decide the plural category.
 * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
 * is shown.
 *
 * Note that when you specify offsets, you must provide explicit number rules for
 * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
 * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
 * plural categories "one" and "other".
 *
 * @param {string|expression} count The variable to be bound to.
 * @param {string} when The mapping between plural category to its corresponding strings.
 * @param {number=} offset Offset to deduct from the total number.
 *
 * @example

        <script>

/**
 * @ngdoc directive
 * @name ngRef
 * @restrict A
 *
 * @description
 * The `ngRef` attribute tells AngularJS to assign the controller of a component (or a directive)
 * to the given property in the current scope. It is also possible to add the jqlite-wrapped DOM
 * element to the scope.
 *
 * If the element with `ngRef` is destroyed `null` is assigned to the property.
 *
 * Note that if you want to assign from a child into the parent scope, you must initialize the
 * target property on the parent scope, otherwise `ngRef` will assign on the child scope.
 * This commonly happens when assigning elements or components wrapped in {@link ngIf} or
 * {@link ngRepeat}. See the second example below.
 *
 *
 * @element ANY
 * @param {string} ngRef property name - A valid AngularJS expression identifier to which the
 *                       controller or jqlite-wrapped DOM element will be bound.
 * @param {string=} ngRefRead read value - The name of a directive (or component) on this element,
 *                            or the special string `$element`. If a name is provided, `ngRef` will
 *                            assign the matching controller. If `$element` is provided, the element
 *                            itself is assigned (even if a controller is available).
 *
 *
 * @example
 * ### Simple toggle
 * This example shows how the controller of the component toggle
 * is reused in the template through the scope to use its logic.
 * <example name="ng-ref-component" module="myApp">
 *   <file name="index.html">
 *     <my-toggle ng-ref="myToggle"></my-toggle>
 *     <button ng-click="myToggle.toggle()">Toggle</button>
 *     <div ng-show="myToggle.isOpen()">
 *       You are using a component in the same template to show it.
 *     </div>
 *   </file>
 *   <file name="index.js">
 *     angular.module('myApp', [])
 *     .component('myToggle', {
 *       controller: function ToggleController() {
 *         var opened = false;
 *         this.isOpen = function() { return opened; };
 *         this.toggle = function() { opened = !opened; };
 *       }
 *     });
 *   </file>
 *   <file name="protractor.js" type="protractor">
 *      it('should publish the toggle into the scope', function() {
 *        var toggle = element(by.buttonText('Toggle'));
 *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(false);
 *        toggle.click();
 *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(true);

 * ### ngRef inside scopes
 * This example shows how `ngRef` works with child scopes. The `ngRepeat`-ed `myWrapper` components
 * are assigned to the scope of `myRoot`, because the `toggles` property has been initialized.
 * The repeated `myToggle` components are published to the child scopes created by `ngRepeat`.
 * `ngIf` behaves similarly - the assignment of `myToggle` happens in the `ngIf` child scope,
 * because the target property has not been initialized on the `myRoot` component controller.
 *
 * <example name="ng-ref-scopes" module="myApp">
 *   <file name="index.html">
 *     <my-root></my-root>
 *   </file>
 *   <file name="index.js">

/* exported ngRepeatDirective */

/**
 * @ngdoc directive
 * @name ngRepeat
 * @multiElement
 * @restrict A
 *
 * @description
 * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
 * instance gets its own scope, where the given loop variable is set to the current collection item,
 * and `$index` is set to the item index or key.
 *
 * Special properties are exposed on the local scope of each template instance, including:
 *
 * | Variable  | Type            | Details                                                                     |
 * |-----------|-----------------|-----------------------------------------------------------------------------|
 * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
 * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
 * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
 * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
 * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
 * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
 *
 * <div class="alert alert-info">
 *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
 *   This may be useful when, for instance, nesting ngRepeats.
 * </div>
 *
 *
 * ## Iterating over object properties
 *
 * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
 * syntax:
 *
 * ```js
 * <div ng-repeat="(key, value) in myObj"> ... </div>
 * ```
 *
 * However, there are a few limitations compared to array iteration:
 *
 * - The JavaScript specification does not define the order of keys
 *   returned for an object, so AngularJS relies on the order returned by the browser
 *   when running `for key in myObj`. Browsers generally follow the strategy of providing
 *   keys in the order in which they were defined, although there are exceptions when keys are deleted
 *   and reinstated. See the
 *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
 *
 * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
 *   it's a prefix used by AngularJS for public (`$`) and private (`$$`) properties.
 *
 * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
 *   objects, and will throw an error if used with one.
 *
 * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
 * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
 * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
 * or implement a `$watch` on the object yourself.
 *
 *
 * ## Tracking and Duplicates
 *
 * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
 * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * To minimize creation of DOM elements, `ngRepeat` uses a function
 * to "keep track" of all items in the collection and their corresponding DOM elements.
 * For example, if an item is added to the collection, `ngRepeat` will know that all other items
 * already have DOM elements, and will not re-render them.
 *
 * All different types of tracking functions, their syntax, and their support for duplicate
 * items in collections can be found in the
 * {@link ngRepeat#ngRepeat-arguments ngRepeat expression description}.
 *
 * <div class="alert alert-success">
 * **Best Practice:** If you are working with objects that have a unique identifier property, you
 * should track by this identifier instead of the object instance,
 * e.g. `item in items track by item.id`.
 * Should you reload your data later, `ngRepeat` will not have to rebuild the DOM elements for items
 * it has already rendered, even if the JavaScript objects in the collection have been substituted
 * for new ones. For large collections, this significantly improves rendering performance.
 * </div>
 *
 * ### Effects of DOM Element re-use
 *
 * When DOM elements are re-used, ngRepeat updates the scope for the element, which will
 * automatically update any active bindings on the template. However, other
 * functionality will not be updated, because the element is not re-created:
 *
 * - Directives are not re-compiled
 * - {@link guide/expression#one-time-binding one-time expressions} on the repeated template are not
 * updated if they have stabilized.
 *
 * The above affects all kinds of element re-use due to tracking, but may be especially visible
 * when tracking by `$index` due to the way ngRepeat re-uses elements.
 *
 * The following example shows the effects of different actions with tracking:

  <example module="ngRepeat" name="ngRepeat-tracking" deps="angular-animate.js" animations="true">
    <file name="script.js">
      angular.module('ngRepeat', ['ngAnimate']).controller('repeatController', function($scope) {
        var friends = [
          {name:'John', age:25},
          {name:'Mary', age:40},
          {name:'Peter', age:85}
        ];

        $scope.removeFirst = function() {
          $scope.friends.shift();
        };

        $scope.updateAge = function() {
          $scope.friends.forEach(function(el) {
            el.age = el.age + 5;
          });
        };

        $scope.copy = function() {
          $scope.friends = angular.copy($scope.friends);
        };

        $scope.reset = function() {
          $scope.friends = angular.copy(friends);
        };

        $scope.reset();
      });
    </file>
    <file name="index.html">
      <div ng-controller="repeatController">
        <ol>
          <li>When you click "Update Age", only the first list updates the age, because all others have
          a one-time binding on the age property. If you then click "Copy", the current friend list
          is copied, and now the second list updates the age, because the identity of the collection items
          has changed and the list must be re-rendered. The 3rd and 4th list stay the same, because all the
          items are already known according to their tracking functions.
          </li>
          <li>When you click "Remove First", the 4th list has the wrong age on both remaining items. This is
          due to tracking by $index: when the first collection item is removed, ngRepeat reuses the first
          DOM element for the new first collection item, and so on. Since the age property is one-time
          bound, the value remains from the collection item which was previously at this index.

 * ## Special repeat start and end points
 * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
 * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
 * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
 * up to and including the ending HTML tag where **ng-repeat-end** is placed.
 *
 * The example below makes use of this feature:
 * ```html
 *   <header ng-repeat-start="item in items">
 *     Header {{ item }}
 *   </header>
 *   <div class="body">
 *     Body {{ item }}
 *   </div>
 *   <footer ng-repeat-end>
 *     Footer {{ item }}
 *   </footer>
 * ```
 *
 * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
 * ```html
 *   <header>
 *     Header A
 *   </header>
 *   <div class="body">
 *     Body A
 *   </div>
 *   <footer>
 *     Footer A
 *   </footer>
 *   <header>
 *     Header B
 *   </header>
 *   <div class="body">
 *     Body B
 *   </div>
 *   <footer>
 *     Footer B
 *   </footer>
 * ```
 *
 * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
 * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).

 *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
 *
 *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
 *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
 *     is specified, ng-repeat associates elements by identity. It is an error to have
 *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
 *     mapped to the same DOM element, which is not possible.)
 *
 *     *Default tracking: $id()*: `item in items` is equivalent to `item in items track by $id(item)`.
 *     This implies that the DOM elements will be associated by item identity in the collection.
 *
 *     The built-in `$id()` function can be used to assign a unique
 *     `$$hashKey` property to each item in the collection. This property is then used as a key to associated DOM elements
 *     with the corresponding item in the collection by identity. Moving the same object would move
 *     the DOM element in the same way in the DOM.
 *     Note that the default id function does not support duplicate primitive values (`number`, `string`),
 *     but supports duplictae non-primitive values (`object`) that are *equal* in shape.
 *
 *     *Custom Expression*: It is possible to use any AngularJS expression to compute the tracking
 *     id, for example with a function, or using a property on the collection items.
 *     `item in items track by item.id` is a typical pattern when the items have a unique identifier,
 *     e.g. database id. In this case the object identity does not matter. Two objects are considered
 *     equivalent as long as their `id` property is same.
 *     Tracking by unique identifier is the most performant way and should be used whenever possible.
 *
 *     *$index*: This special property tracks the collection items by their index, and
 *     re-uses the DOM elements that match that index, e.g. `item in items track by $index`. This can
 *     be used for a performance improvement if no unique identfier is available and the identity of
 *     the collection items cannot be easily computed. It also allows duplicates.
 *
 *     <div class="alert alert-warning">
 *       <strong>Note:</strong> Re-using DOM elements can have unforeseen effects. Read the
 *       {@link ngRepeat#tracking-and-duplicates section on tracking and duplicates} for
 *       more info.
 *     </div>
 *
 *     <div class="alert alert-warning">
 *       <strong>Note:</strong> the `track by` expression must come last - after any filters, and the alias expression:
 *       `item in items | filter:searchText as results  track by item.id`
 *     </div>
 *
 *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
 *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
 *     when a filter is active on the repeater, but the filtered result set is empty.
 *
 *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
 *     the items have been processed through the filter.
 *
 *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat
 *     micro-syntax so it can be used only after all filters (and not as operator, inside an expression).
 *
 *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results track by item.id` .
 *
 * @example
 * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
 * results by name or by age. New (entering) and removed (leaving) items are animated.

/**
 * @ngdoc directive
 * @name ngShow
 * @multiElement
 *
 * @description
 * The `ngShow` directive shows or hides the given HTML element based on the expression provided to
 * the `ngShow` attribute.
 *
 * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
 * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
 * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
 * {@link ng.directive:ngCsp ngCsp}).
 *
 * ```html
 * <!-- when $scope.myValue is truthy (element is visible) -->
 * <div ng-show="myValue"></div>
 *
 * <!-- when $scope.myValue is falsy (element is hidden) -->
 * <div ng-show="myValue" class="ng-hide"></div>
 * ```
 *
 * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
 * to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
 * CSS class is removed from the element causing the element not to appear hidden.
 *
 * ## Why is `!important` used?
 *
 * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
 * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
 * simple as changing the display style on a HTML list item would make hidden elements appear
 * visible. This also becomes a bigger issue when dealing with CSS frameworks.
 *
 * By using `!important`, the show and hide behavior will work as expected despite any clash between
 * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
 * developer chooses to override the styling to change how to hide an element then it is just a
 * matter of using `!important` in their own CSS code.
 *
 * ### Overriding `.ng-hide`
 *
 * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
 * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
 * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
 * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
 *
 * ```css
 * .ng-hide:not(.ng-hide-animate) {
 *   /&#42; These are just alternative ways of hiding an element &#42;/
 *   display: block!important;
 *   position: absolute;
 *   top: -9999px;
 *   left: -9999px;
 * }
 * ```
 *
 * By default you don't need to override anything in CSS and the animations will work around the
 * display style.
 *
 * @animations
 * | Animation                                           | Occurs                                                                                                        |
 * |-----------------------------------------------------|---------------------------------------------------------------------------------------------------------------|
 * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden. |
 * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngShow` expression evaluates to a truthy value and just before contents are set to visible.        |
 *
 * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
 * directive expression is true and false. This system works like the animation system present with
 * `ngClass` except that you must also include the `!important` flag to override the display
 * property so that the elements are not actually hidden during the animation.
 *
 * ```css
 * /&#42; A working example can be found at the bottom of this page. &#42;/
 * .my-element.ng-hide-add, .my-element.ng-hide-remove {
 *   transition: all 0.5s linear;
 * }
 *

/**
 * @ngdoc directive
 * @name ngHide
 * @multiElement
 *
 * @description
 * The `ngHide` directive shows or hides the given HTML element based on the expression provided to
 * the `ngHide` attribute.
 *
 * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
 * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
 * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
 * {@link ng.directive:ngCsp ngCsp}).
 *
 * ```html
 * <!-- when $scope.myValue is truthy (element is hidden) -->
 * <div ng-hide="myValue" class="ng-hide"></div>
 *
 * <!-- when $scope.myValue is falsy (element is visible) -->
 * <div ng-hide="myValue"></div>
 * ```
 *
 * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added
 * to the class attribute on the element causing it to become hidden. When falsy, the `.ng-hide`
 * CSS class is removed from the element causing the element not to appear hidden.
 *
 * ## Why is `!important` used?
 *
 * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
 * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
 * simple as changing the display style on a HTML list item would make hidden elements appear
 * visible. This also becomes a bigger issue when dealing with CSS frameworks.
 *
 * By using `!important`, the show and hide behavior will work as expected despite any clash between
 * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
 * developer chooses to override the styling to change how to hide an element then it is just a
 * matter of using `!important` in their own CSS code.
 *
 * ### Overriding `.ng-hide`
 *
 * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
 * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
 * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
 * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
 *
 * ```css
 * .ng-hide:not(.ng-hide-animate) {
 *   /&#42; These are just alternative ways of hiding an element &#42;/
 *   display: block!important;
 *   position: absolute;
 *   top: -9999px;
 *   left: -9999px;
 * }
 * ```
 *
 * By default you don't need to override in CSS anything and the animations will work around the
 * display style.
 *
 * @animations
 * | Animation                                           | Occurs                                                                                                     |
 * |-----------------------------------------------------|------------------------------------------------------------------------------------------------------------|
 * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden.  |
 * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngHide` expression evaluates to a non truthy value and just before contents are set to visible. |
 *
 * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
 * directive expression is true and false. This system works like the animation system present with
 * `ngClass` except that you must also include the `!important` flag to override the display
 * property so that the elements are not actually hidden during the animation.
 *
 * ```css
 * /&#42; A working example can be found at the bottom of this page. &#42;/
 * .my-element.ng-hide-add, .my-element.ng-hide-remove {
 *   transition: all 0.5s linear;

/**
 * @ngdoc directive

 * @restrict EA
 *
 * @description
 * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
 * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
 * as specified in the template.
 *
 * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
 * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
 * matches the value obtained from the evaluated expression. In other words, you define a container element
 * (where you place the directive), place an expression on the **`on="..."` attribute**
 * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
 * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
 * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
 * attribute is displayed.
 *
 * <div class="alert alert-info">
 * Be aware that the attribute values to match against cannot be expressions. They are interpreted
 * as literal string values to match against.
 * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
 * value of the expression `$scope.someVal`.
 * </div>

 * On child elements add:
 *
 * * `ngSwitchWhen`: the case statement to match against. If match then this
 *   case will be displayed. If the same match appears multiple times, all the
 *   elements will be displayed. It is possible to associate multiple values to
 *   the same `ngSwitchWhen` by defining the optional attribute
 *   `ngSwitchWhenSeparator`. The separator will be used to split the value of
 *   the `ngSwitchWhen` attribute into multiple tokens, and the element will show
 *   if any of the `ngSwitch` evaluates to any of these tokens.
 * * `ngSwitchDefault`: the default case when no other case match. If there
 *   are multiple default cases, all of them will be displayed when no other
 *   case match.

/**
 * @ngdoc directive
 * @name ngTransclude
 * @restrict EAC
 *
 * @description
 * Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
 *
 * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
 * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
 *
 * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
 * content of this element will be removed before the transcluded content is inserted.
 * If the transcluded content is empty (or only whitespace), the existing content is left intact. This lets you provide fallback
 * content in the case that no transcluded content is provided.
 *
 * @element ANY
 *
 * @param {string} ngTransclude|ngTranscludeSlot the name of the slot to insert at this point. If this is not provided, is empty
 *                                               or its value is the same as the name of the attribute then the default slot is used.
 *
 * @example
 * ### Basic transclusion
 * This example demonstrates basic transclusion of content into a component directive.
 * <example name="simpleTranscludeExample" module="transcludeExample">
 *   <file name="index.html">
 *     <script>

 *
 * @example
 * ### Set a custom error when the unknown option is selected
 *
 * This example sets a custom error "unknownValue" on the ngModelController
 * when the select element's unknown option is selected, i.e. when the model is set to a value
 * that is not matched by any option.
 *
 * <example name="select-unknown-value-error" module="staticSelect">
 * <file name="index.html">
 * <div ng-controller="ExampleController">
 *   <form name="myForm">
 *     <label for="testSelect"> Single select: </label><br>
 *     <select name="testSelect" ng-model="selected" unknown-value-error>

 *     </select><br>
 *     <span class="error" ng-if="myForm.testSelect.$error.unknownValue">
 *       Error: The current model doesn't match any option</span><br>
 *
 *     <button ng-click="forceUnknownOption()">Force unknown option</button><br>
 *   </form>
 * </div>
 * </file>
 * <file name="app.js">
 *  angular.module('staticSelect', [])
 *    .controller('ExampleController', ['$scope', function($scope) {
 *      $scope.selected = null;
 *
 *      $scope.forceUnknownOption = function() {
 *        $scope.selected = 'nonsense';
 *      };
 *   }])
 *   .directive('unknownValueError', function() {

 *         };
 *       }
 *
 *     };
 *   });
 * </file>
 *</example>
 *
 *
 * @example
 * ### Set the "required" error when the unknown option is selected.
 *
 * By default, the "required" error on the ngModelController is only set on a required select
 * when the empty option is selected. This example adds a custom directive that also sets the
 * error when the unknown option is selected.
 *
 * <example name="select-unknown-value-required" module="staticSelect">

 *       <option value="option-1">Option 1</option>
 *       <option value="option-2">Option 2</option>
 *     </select><br>
 *     <span class="error" ng-if="myForm.testSelect.$error.required">Error: Please select a value</span><br>

 *        $scope.selected = 'nonsense';
 *      };
 *   }])
 *   .directive('unknownValueRequired', function() {
 *     return {
 *       priority: 1, // This directive must run after the required directive has added its validator
 *       require: ['ngModel', 'select'],

 *
 *         var originalRequiredValidator = ngModelCtrl.$validators.required;
 *
 *         ngModelCtrl.$validators.required = function() {
 *           if (attrs.required && selectCtrl.$isUnknownOptionSelected()) {
 *             return false;
 *           }
 *
 *           return originalRequiredValidator.apply(this, arguments);

/**
 * @ngdoc directive
 * @name select
 * @restrict E
 *
 * @description
 * HTML `select` element with AngularJS data-binding.
 *
 * The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
 * between the scope and the `<select>` control (including setting default values).
 * It also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
 * {@link ngOptions `ngOptions`} directives.
 *
 * When an item in the `<select>` menu is selected, the value of the selected option will be bound
 * to the model identified by the `ngModel` directive. With static or repeated options, this is
 * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
 * Value and textContent can be interpolated.
 *
 * The {@link select.SelectController select controller} exposes utility functions that can be used
 * to manipulate the select's behavior.
 *
 * ## Matching model and option values
 *
 * In general, the match between the model and an option is evaluated by strictly comparing the model
 * value against the value of the available options.
 *
 * If you are setting the option value with the option's `value` attribute, or textContent, the
 * value will always be a `string` which means that the model value must also be a string.
 * Otherwise the `select` directive cannot match them correctly.
 *
 * To bind the model to a non-string value, you can use one of the following strategies:
 * - the {@link ng.ngOptions `ngOptions`} directive
 *   ({@link ng.select#using-select-with-ngoptions-and-setting-a-default-value})
 * - the {@link ng.ngValue `ngValue`} directive, which allows arbitrary expressions to be
 *   option values ({@link ng.select#using-ngvalue-to-bind-the-model-to-an-array-of-objects Example})
 * - model $parsers / $formatters to convert the string value
 *   ({@link ng.select#binding-select-to-a-non-string-value-via-ngmodel-parsing-formatting Example})
 *
 * If the viewValue of `ngModel` does not match any of the options, then the control
 * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
 *
 * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
 * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
 * option. See example below for demonstration.
 *
 * ## Choosing between `ngRepeat` and `ngOptions`
 *
 * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
 * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits:
 * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
 * comprehension expression
 * - reduced memory consumption by not creating a new scope for each repeated instance
 * - increased render speed by creating the options in a documentFragment instead of individually
 *
 * Specifically, select with repeated options slows down significantly starting at 2000 options in
 * Chrome and Internet Explorer / Edge.
 *
 *
 * @param {string} ngModel Assignable AngularJS expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} multiple Allows multiple options to be selected. The selected values will be
 *     bound to the model as an array.
 * @param {string=} required Sets `required` validation error key if the value is not entered.
 * @param {string=} ngRequired Adds required attribute and required validation constraint to
 * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
 * when you want to data-bind to the required attribute.
 * @param {string=} ngChange AngularJS expression to be executed when selected option(s) changes due to user
 *    interaction with the select element.
 * @param {string=} ngOptions sets the options that the select is populated with and defines what is
 * set on the model on selection. See {@link ngOptions `ngOptions`}.
 * @param {string=} ngAttrSize sets the size of the select element dynamically. Uses the
 * {@link guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes ngAttr} directive.

/**
 * @ngdoc directive
 * @name ngRequired
 * @restrict A
 *
 * @param {expression} ngRequired AngularJS expression. If it evaluates to `true`, it sets the
 *                                `required` attribute to the element and adds the `required`
 *                                {@link ngModel.NgModelController#$validators `validator`}.
 *
 * @description
 *
 * ngRequired adds the required {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
 * It is most often used for {@link input `input`} and {@link select `select`} controls, but can also be
 * applied to custom controls.
 *
 * The directive sets the `required` attribute on the element if the AngularJS expression inside
 * `ngRequired` evaluates to true. A special directive for setting `required` is necessary because we
 * cannot use interpolation inside `required`. See the {@link guide/interpolation interpolation guide}
 * for more info.
 *
 * The validator will set the `required` error key to true if the `required` attribute is set and
 * calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the
 * {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the
 * `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing
 * custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.
 *

 * It is most often used for text-based {@link input `input`} controls, but can also be applied to custom text-based controls.
 *
 * The validator sets the `pattern` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}
 * does not match a RegExp which is obtained from the `ngPattern` attribute value:
 * - the value is an AngularJS expression:
 *   - If the expression evaluates to a RegExp object, then this is used directly.
 *   - If the expression evaluates to a string, then it will be converted to a RegExp after wrapping it
 *     in `^` and `$` characters. For instance, `"abc"` will be converted to `new RegExp('^abc$')`.
 * - If the value is a RegExp literal, e.g. `ngPattern="/^\d+$/"`, it is used directly.
 *
 * <div class="alert alert-info">
 * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

 **/

/**
 * new MarkdownIt([presetName, options])
 * - presetName (String): optional, `commonmark` / `zero`
 * - options (Object)
 *
 * Creates parser instanse with given config. Can be called without `new`.
 *
 * ##### presetName
 *
 * MarkdownIt provides named presets as a convenience to quickly
 * enable/disable active syntax rules and options for common use cases.
 *
 * - ["commonmark"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -
 *   configures parser to strict [CommonMark](http://commonmark.org/) mode.
 * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -
 *   similar to GFM, used when no preset name given. Enables all available rules,
 *   but still without html, typographer & autolinker.
 * - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -
 *   all rules disabled. Useful to quickly setup your config via `.enable()`.
 *   For example, when you need only `bold` and `italic` markup and nothing else.
 *
 * ##### options:
 *
 * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!
 *   That's not safe! You may need external sanitizer to protect output from XSS.
 *   It's better to extend features via plugins, instead of enabling HTML.
 * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags
 *   (`<br />`). This is needed only for full CommonMark compatibility. In real
 *   world you will need HTML output.
 * - __breaks__ - `false`. Set `true` to convert `\n` in paragraphs into `<br>`.
 * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.
 *   Can be useful for external highlighters.
 * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.
 * - __typographer__  - `false`. Set `true` to enable [some language-neutral
 *   replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +
 *   quotes beautification (smartquotes).
 * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement
 *   pairs, when typographer enabled and smartquotes on. For example, you can
 *   use `'«»„“'` for Russian, `'„“‚‘'` for German, and
 *   `['«\xA0', '\xA0»', '‹\xA0', '\xA0›']` for French (including nbsp).
 * - __highlight__ - `null`. Highlighter function for fenced code blocks.
 *   Highlighter `function (str, lang)` should return escaped HTML. It can also
 *   return empty string if the source was not changed and should be escaped
 *   externaly. If result starts with <pre... internal wrapper is skipped.
 *
 * ##### Example
 *
 * ```javascript
 * // commonmark mode
 * var md = require('markdown-it')('commonmark');
 *
 * // default mode
 * var md = require('markdown-it')();
 *
 * // enable everything
 * var md = require('markdown-it')({
 *   html: true,
 *   linkify: true,
 *   typographer: true
 * });
 * ```
 *
 * ##### Syntax highlighting
 *
 * ```js
 * var hljs = require('highlight.js') // https://highlightjs.org/
 *
 * var md = require('markdown-it')({
 *   highlight: function (str, lang) {
 *     if (lang && hljs.getLanguage(lang)) {
 *       try {
 *         return hljs.highlight(lang, str, true).value;
 *       } catch (__) {}
 *     }
 *
 *     return ''; // use external default escaping
 *   }
 * });
 * ```
 *
 * Or with full wrapper override (if you need assign class to `<pre>`):
 *
 * ```javascript
 * var hljs = require('highlight.js') // https://highlightjs.org/
 *
 * // Actual default values
 * var md = require('markdown-it')({
 *   highlight: function (str, lang) {
 *     if (lang && hljs.getLanguage(lang)) {
 *       try {
 *         return '<pre class="hljs"><code>' +
 *                hljs.highlight(lang, str, true).value +
 *                '</code></pre>';
 *       } catch (__) {}
 *     }
 *
 *     return '<pre class="hljs"><code>' + md.utils.escapeHtml(str) + '</code></pre>';
 *   }
 * });
 * ```

// Changes from joyent/node:
//
// 1. No leading slash in paths,
//    e.g. in `url.parse('http://foo?bar')` pathname is ``, not `/`
//
// 2. Backslashes are not replaced with slashes,
//    so `http:\\example.org\` is treated like a relative path
//
// 3. Trailing colon is treated like a part of the path,
//    i.e. in `http://example.org:foo` pathname is `:foo`
//
// 4. Nothing is URL-encoded in the resulting object,
//    (in joyent/node some chars in auth and paths are encoded)
//
// 5. `url.parse()` does not have `parseQueryString` argument
//
// 6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
//    which can be constructed using other parts of the url.
//

 * - schemas (Object): Optional. Additional schemas to validate (prefix/validator)
 * - options (Object): { fuzzyLink|fuzzyEmail|fuzzyIP: true|false }
 *
 * Creates new linkifier instance with optional additional schemas.
 * Can be called without `new` keyword for convenience.
 *
 * By default understands:
 *
 * - `http(s)://...` , `ftp://...`, `mailto:...` & `//...` links
 * - "fuzzy" links and emails (example.com, foo@bar.com).
 *
 * `schemas` is an object, where each key/value describes protocol/rule:
 *
 * - __key__ - link prefix (usually, protocol name with `:` at the end, `skype:`
 *   for example). `linkify-it` makes shure that prefix is not preceeded with
 *   alphanumeric char and symbols. Only whitespaces and punctuation allowed.
 * - __value__ - rule to check tail after link prefix
 *   - _String_ - just alias to existing rule
 *   - _Object_
 *     - _validate_ - validator function (should return matched length on success),
 *       or `RegExp`.
 *     - _normalize_ - optional function to normalize text & url of matched result
 *       (for example, for @twitter mentions).
 *
 * `options`:
 *
 * - __fuzzyLink__ - recognige URL-s without `http(s):` prefix. Default `true`.
 * - __fuzzyIP__ - allow IPs in fuzzy links above. Can conflict with some texts
 *   like version numbers. Default `false`.
 * - __fuzzyEmail__ - recognize emails without `mailto:` prefix.

 *
 * ### Deprecation warning:
 *
 * The value injected for `$stateParams` is different depending on where it is injected.
 *
 * - When injected into an angular service, the object injected is the global **Service Object** with the parameter values for the latest successful `Transition`.
 * - When injected into transition hooks, resolves, or view controllers, the object is the **Per-Transition Object** with the parameter values for the running `Transition`.
 *
 * Because of these confusing details, this service is deprecated.
 *
 * ### Instead of using the global `$stateParams` service object,
 * inject [[$uiRouterGlobals]] and use [[UIRouterGlobals.params]]
 *
 * ```js
 * MyService.$inject = ['$uiRouterGlobals'];
 * function MyService($uiRouterGlobals) {
 *   return {
 *     paramValues: function () {
 *       return $uiRouterGlobals.params;
 *     }
 *   }
 * }
 * ```
 *
 * ### Instead of using the per-transition `$stateParams` object,
 * inject the current `Transition` (as [[$transition$]]) and use [[Transition.params]]
 *
 * ```js
 * MyController.$inject = ['$transition$'];
 * function MyController($transition$) {
 *   var username = $transition$.params().username;
 *   // .. do something with username
 * }
 * ```
 *
 * ---
 *
 * This object can be injected into other services.
 *
 * #### Deprecated Example:
 * ```js
 * SomeService.$inject = ['$http', '$stateParams'];
 * function SomeService($http, $stateParams) {
 *   return {
 *     getUser: function() {
 *       return $http.get('/api/users/' + $stateParams.username);

 *
 * Requires the {@link ngSanitize `ngSanitize`} module to be installed.
 *
 * @param {string} text Input text.
 * @param {string} [target] Window (`_blank|_self|_parent|_top`) or named frame to open links in.
 * @param {object|function(url)} [attributes] Add custom attributes to the link element.
 *
 *    Can be one of:
 *
 *    - `object`: A map of attributes
 *    - `function`: Takes the url as a parameter and returns a map of attributes
 *
 *    If the map of attributes contains a value for `target`, it overrides the value of

/**
 * @ngdoc service
 * @name $animateCss
 * @kind object
 *
 * @description
 * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
 * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
 * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
 * directives to create more complex animations that can be purely driven using CSS code.
 *
 * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
 * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
 *
 * ## General Use
 * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
 * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
 * any automatic control over cancelling animations and/or preventing animations from being run on
 * child elements will not be handled by AngularJS. For this to work as expected, please use `$animate` to
 * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
 * the CSS animation.
 *
 * The example below shows how we can create a folding animation on an element using `ng-if`:
 *
 * ```html
 * <!-- notice the `fold-animation` CSS class -->
 * <div ng-if="onOff" class="fold-animation">
 *   This element will go BOOM
 * </div>
 * <button ng-click="onOff=true">Fold In</button>
 * ```
 *
 * Now we create the **JavaScript animation** that will trigger the CSS transition:
 *
 * ```js
 * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element, doneFn) {
 *       var height = element[0].offsetHeight;
 *       return $animateCss(element, {
 *         from: { height:'0px' },
 *         to: { height:height + 'px' },
 *         duration: 1 // one second
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * ## More Advanced Uses
 *
 * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
 * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
 *
 * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
 * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
 * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
 * to provide a working animation that will run in CSS.
 *
 * The example below showcases a more advanced version of the `.fold-animation` from the example above:
 *
 * ```js
 * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element, doneFn) {
 *       var height = element[0].offsetHeight;
 *       return $animateCss(element, {
 *         addClass: 'red large-text pulse-twice',
 *         easing: 'ease-out',
 *         from: { height:'0px' },
 *         to: { height:height + 'px' },
 *         duration: 1 // one second
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
 *
 * ```css
 * /&#42; since a hardcoded duration value of 1 was provided in the JavaScript animation code,
 * the CSS classes below will be transitioned despite them being defined as regular CSS classes &#42;/
 * .red { background:red; }
 * .large-text { font-size:20px; }
 *
 * /&#42; we can also use a keyframe animation and $animateCss will make it work alongside the transition &#42;/
 * .pulse-twice {
 *   animation: 0.5s pulse linear 2;
 *   -webkit-animation: 0.5s pulse linear 2;
 * }
 *
 * @keyframes pulse {
 *   from { transform: scale(0.5); }
 *   to { transform: scale(1.5); }
 * }
 *
 * @-webkit-keyframes pulse {
 *   from { -webkit-transform: scale(0.5); }
 *   to { -webkit-transform: scale(1.5); }
 * }
 * ```
 *
 * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
 *
 * ## How the Options are handled
 *
 * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
 * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
 * styles using the `from` and `to` properties.
 *
 * ```js
 * var animator = $animateCss(element, {
 *   from: { background:'red' },
 *   to: { background:'blue' }
 * });
 * animator.start();
 * ```
 *
 * ```css
 * .rotating-animation {
 *   animation:0.5s rotate linear;
 *   -webkit-animation:0.5s rotate linear;
 * }
 *
 * @keyframes rotate {
 *   from { transform: rotate(0deg); }
 *   to { transform: rotate(360deg); }
 * }
 *
 * @-webkit-keyframes rotate {
 *   from { -webkit-transform: rotate(0deg); }
 *   to { -webkit-transform: rotate(360deg); }
 * }
 * ```
 *
 * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
 * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
 * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
 * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
 * and spread across the transition and keyframe animation.
 *
 * ## What is returned
 *
 * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
 * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
 * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
 *
 * ```js
 * var animator = $animateCss(element, { ... });
 * ```
 *
 * Now what do the contents of our `animator` variable look like:
 *
 * ```js
 * {
 *   // starts the animation
 *   start: Function,
 *
 *   // ends (aborts) the animation
 *   end: Function
 * }
 * ```
 *
 * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
 * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been
 * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
 * and that changing them will not reconfigure the parameters of the animation.
 *
 * ### runner.done() vs runner.then()
 * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
 * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
 * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
 * unless you really need a digest to kick off afterwards.
 *
 * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
 * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
 * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
 *
 * @param {DOMElement} element the element that will be animated
 * @param {object} options the animation-related options that will be applied during the animation
 *
 * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
 * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
 * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
 * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
 * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
 * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
 * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
 * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
 * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
 * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
 * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
 * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
 * is provided then the animation will be skipped entirely.
 * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
 * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
 * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
 * CSS delay value.
 * * `stagger` - A numeric time value representing the delay between successively animated elements
 * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
 * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
 *   `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
 * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.)
 * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
 *    the animation is closed. This is useful for when the styles are used purely for the sake of
 *    the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
 *    By default this value is set to `false`.
 *
 * @return {object} an object with start and end methods and details about the animation.
 *
 * * `start` - The method to start the animation. This will return a `Promise` when called.
 * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

 * common usecase for this directive is a rotating banner or slider component which
 * contains one image being present at a time. When the active image changes
 * then the old image will perform a `leave` animation and the new element
 * will be inserted via an `enter` animation.

/**
 * @ngdoc module
 * @name ngAnimate
 * @description
 *
 * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
 * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an AngularJS app.
 *
 * ## Usage
 * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
 * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
 * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
 * the HTML element that the animation will be triggered on.
 *
 * ## Directive Support
 * The following directives are "animation aware":
 *
 * | Directive                                                                     | Supported Animations                                                      |

 * | {@link ngAnimate.directive:ngAnimateSwap#animations ngAnimateSwap}            | enter and leave                                                           |
 * | {@link ng.directive:ngClass#animations ngClass / {{class&#125;&#8203;&#125;}  | add and remove                                                            |

 * | {@link ng.directive:ngIf#animations ngIf}                                     | enter and leave                                                           |

 * | {@link ng.directive:ngRepeat#animations ngRepeat}                             | enter, leave, and move                                                    |
 * | {@link ng.directive:ngShow#animations ngShow}                                 | add and remove (the `ng-hide` class)                                      |
 * | {@link ng.directive:ngSwitch#animations ngSwitch}                             | enter and leave                                                           |

 *
 * (More information can be found by visiting the documentation associated with each directive.)
 *
 * For a full breakdown of the steps involved during each animation event, refer to the
 * {@link ng.$animate `$animate` API docs}.
 *
 * ## CSS-based Animations
 *
 * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
 * and CSS code we can create an animation that will be picked up by AngularJS when an underlying directive performs an operation.
 *
 * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
 *
 * ```html
 * <div ng-if="bool" class="fade">
 *    Fade me in out
 * </div>
 * <button ng-click="bool=true">Fade In!</button>
 * <button ng-click="bool=false">Fade Out!</button>
 * ```
 *
 * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
 *
 * ```css
 * /&#42; The starting CSS styles for the enter animation &#42;/
 * .fade.ng-enter {
 *   transition:0.5s linear all;
 *   opacity:0;
 * }
 *
 * /&#42; The finishing CSS styles for the enter animation &#42;/
 * .fade.ng-enter.ng-enter-active {
 *   opacity:1;
 * }
 * ```
 *
 * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
 * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
 * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
 *
 * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
 *
 * ```css
 * /&#42; now the element will fade out before it is removed from the DOM &#42;/
 * .fade.ng-leave {
 *   transition:0.5s linear all;
 *   opacity:1;
 * }
 * .fade.ng-leave.ng-leave-active {
 *   opacity:0;
 * }
 * ```
 *
 * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
 *
 * ```css
 * /&#42; there is no need to define anything inside of the destination
 * CSS class since the keyframe will take charge of the animation &#42;/
 * .fade.ng-leave {
 *   animation: my_fade_animation 0.5s linear;
 *   -webkit-animation: my_fade_animation 0.5s linear;
 * }
 *
 * @keyframes my_fade_animation {
 *   from { opacity:1; }
 *   to { opacity:0; }
 * }
 *
 * @-webkit-keyframes my_fade_animation {
 *   from { opacity:1; }
 *   to { opacity:0; }
 * }
 * ```
 *
 * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
 *
 * ### CSS Class-based Animations
 *
 * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
 * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
 * and removed.
 *
 * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
 *
 * ```html
 * <div ng-show="bool" class="fade">
 *   Show and hide me
 * </div>
 * <button ng-click="bool=!bool">Toggle</button>
 *
 * <style>
 * .fade.ng-hide {
 *   transition:0.5s linear all;
 *   opacity:0;
 * }
 * </style>
 * ```
 *
 * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
 * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
 *
 * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
 * with CSS styles.
 *
 * ```html
 * <div ng-class="{on:onOff}" class="highlight">
 *   Highlight this box
 * </div>
 * <button ng-click="onOff=!onOff">Toggle</button>
 *
 * <style>
 * .highlight {
 *   transition:0.5s linear all;
 * }
 * .highlight.on-add {
 *   background:white;
 * }
 * .highlight.on {
 *   background:yellow;
 * }
 * .highlight.on-remove {
 *   background:black;
 * }
 * </style>
 * ```
 *
 * We can also make use of CSS keyframes by placing them within the CSS classes.
 *
 *
 * ### CSS Staggering Animations
 * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
 * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
 * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
 * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
 * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
 *
 * ```css
 * .my-animation.ng-enter {
 *   /&#42; standard transition code &#42;/
 *   transition: 1s linear all;
 *   opacity:0;
 * }
 * .my-animation.ng-enter-stagger {
 *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
 *   transition-delay: 0.1s;
 *
 *   /&#42; As of 1.4.4, this must always be set: it signals ngAnimate
 *     to not accidentally inherit a delay property from another CSS class &#42;/
 *   transition-duration: 0s;
 *
 *   /&#42; if you are using animations instead of transitions you should configure as follows:
 *     animation-delay: 0.1s;
 *     animation-duration: 0s; &#42;/
 * }
 * .my-animation.ng-enter.ng-enter-active {
 *   /&#42; standard transition styles &#42;/
 *   opacity:1;
 * }
 * ```
 *
 * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
 * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
 * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
 * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
 *
 * The following code will issue the **ng-leave-stagger** event on the element provided:
 *
 * ```js
 * var kids = parent.children();
 *
 * $animate.leave(kids[0]); //stagger index=0
 * $animate.leave(kids[1]); //stagger index=1
 * $animate.leave(kids[2]); //stagger index=2
 * $animate.leave(kids[3]); //stagger index=3
 * $animate.leave(kids[4]); //stagger index=4
 *
 * window.requestAnimationFrame(function() {
 *   //stagger has reset itself
 *   $animate.leave(kids[5]); //stagger index=0
 *   $animate.leave(kids[6]); //stagger index=1
 *
 *   $scope.$digest();
 * });
 * ```
 *
 * Stagger animations are currently only supported within CSS-defined animations.
 *
 * ### The `ng-animate` CSS class
 *
 * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
 * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
 *
 * Therefore, animations can be applied to an element using this temporary class directly via CSS.
 *
 * ```css
 * .zipper.ng-animate {
 *   transition:0.5s linear all;
 * }
 * .zipper.ng-enter {
 *   opacity:0;
 * }
 * .zipper.ng-enter.ng-enter-active {
 *   opacity:1;
 * }
 * .zipper.ng-leave {
 *   opacity:1;
 * }
 * .zipper.ng-leave.ng-leave-active {
 *   opacity:0;
 * }
 * ```
 *
 * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
 * the CSS class once an animation has completed.)
 *
 *
 * ### The `ng-[event]-prepare` class
 *
 * This is a special class that can be used to prevent unwanted flickering / flash of content before
 * the actual animation starts. The class is added as soon as an animation is initialized, but removed
 * before the actual animation starts (after waiting for a $digest).
 * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
 *
 * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
 * into elements that have class-based animations such as `ngClass`.
 *
 * ```html
 * <div ng-class="{red: myProp}">
 *   <div ng-class="{blue: myProp}">
 *     <div class="message" ng-if="myProp"></div>
 *   </div>
 * </div>
 * ```
 *
 * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
 * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
 *
 * ```css
 * .message.ng-enter-prepare {
 *   opacity: 0;
 * }
 * ```
 *
 * ### Animating between value changes
 *
 * Sometimes you need to animate between different expression states, whose values
 * don't necessary need to be known or referenced in CSS styles.
 * Unless possible with another {@link ngAnimate#directive-support "animation aware" directive},
 * that specific use case can always be covered with {@link ngAnimate.directive:ngAnimateSwap} as
 * can be seen in {@link ngAnimate.directive:ngAnimateSwap#examples this example}.
 *
 * Note that {@link ngAnimate.directive:ngAnimateSwap} is a *structural directive*, which means it
 * creates a new instance of the element (including any other/child directives it may have) and
 * links it to a new scope every time *swap* happens. In some cases this might not be desirable
 * (e.g. for performance reasons, or when you wish to retain internal state on the original
 * element instance).
 *
 * ## JavaScript-based Animations
 *
 * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
 * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
 * `module.animation()` module function we can register the animation.
 *
 * Let's see an example of a enter/leave animation using `ngRepeat`:
 *
 * ```html
 * <div ng-repeat="item in items" class="slide">
 *   {{ item }}
 * </div>
 * ```
 *
 * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
 *
 * ```js
 * myModule.animation('.slide', [function() {
 *   return {
 *     // make note that other events (like addClass/removeClass)
 *     // have different function input parameters
 *     enter: function(element, doneFn) {
 *       jQuery(element).fadeIn(1000, doneFn);
 *
 *       // remember to call doneFn so that AngularJS
 *       // knows that the animation has concluded
 *     },
 *
 *     move: function(element, doneFn) {
 *       jQuery(element).fadeIn(1000, doneFn);
 *     },
 *
 *     leave: function(element, doneFn) {
 *       jQuery(element).fadeOut(1000, doneFn);
 *     }
 *   }
 * }]);
 * ```
 *
 * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
 * greensock.js and velocity.js.
 *
 * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
 * our animations inside of the same registered animation, however, the function input arguments are a bit different:
 *
 * ```html
 * <div ng-class="color" class="colorful">
 *   this box is moody
 * </div>
 * <button ng-click="color='red'">Change to red</button>
 * <button ng-click="color='blue'">Change to blue</button>
 * <button ng-click="color='green'">Change to green</button>
 * ```
 *
 * ```js
 * myModule.animation('.colorful', [function() {
 *   return {
 *     addClass: function(element, className, doneFn) {
 *       // do some cool animation and call the doneFn
 *     },
 *     removeClass: function(element, className, doneFn) {
 *       // do some cool animation and call the doneFn
 *     },
 *     setClass: function(element, addedClass, removedClass, doneFn) {
 *       // do some cool animation and call the doneFn
 *     }
 *   }
 * }]);
 * ```
 *
 * ## CSS + JS Animations Together
 *
 * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of AngularJS,
 * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
 * charge of the animation**:
 *
 * ```html
 * <div ng-if="bool" class="slide">
 *   Slide in and out
 * </div>
 * ```
 *
 * ```js
 * myModule.animation('.slide', [function() {
 *   return {
 *     enter: function(element, doneFn) {
 *       jQuery(element).slideIn(1000, doneFn);
 *     }
 *   }
 * }]);
 * ```
 *
 * ```css
 * .slide.ng-enter {
 *   transition:0.5s linear all;
 *   transform:translateY(-100px);
 * }
 * .slide.ng-enter.ng-enter-active {
 *   transform:translateY(0);
 * }
 * ```
 *
 * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
 * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
 * our own JS-based animation code:
 *
 * ```js
 * myModule.animation('.slide', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element) {
*        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
 *       return $animateCss(element, {
 *         event: 'enter',
 *         structural: true
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
 *
 * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
 * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
 * data into `$animateCss` directly:
 *
 * ```js
 * myModule.animation('.slide', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element) {
 *       return $animateCss(element, {
 *         event: 'enter',
 *         structural: true,
 *         addClass: 'maroon-setting',
 *         from: { height:0 },
 *         to: { height: 200 }
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * Now we can fill in the rest via our transition CSS code:
 *
 * ```css
 * /&#42; the transition tells ngAnimate to make the animation happen &#42;/
 * .slide.ng-enter { transition:0.5s linear all; }
 *
 * /&#42; this extra CSS class will be absorbed into the transition
 * since the $animateCss code is adding the class &#42;/
 * .maroon-setting { background:red; }
 * ```
 *
 * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
 *
 * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
 *
 * ## Animation Anchoring (via `ng-animate-ref`)
 *
 * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
 * structural areas of an application (like views) by pairing up elements using an attribute
 * called `ng-animate-ref`.
 *
 * Let's say for example we have two views that are managed by `ng-view` and we want to show
 * that there is a relationship between two components situated in within these views. By using the
 * `ng-animate-ref` attribute we can identify that the two components are paired together and we
 * can then attach an animation, which is triggered when the view changes.
 *
 * Say for example we have the following template code:
 *
 * ```html
 * <!-- index.html -->
 * <div ng-view class="view-animation">
 * </div>
 *
 * <!-- home.html -->
 * <a href="#/banner-page">
 *   <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
 * </a>
 *
 * <!-- banner-page.html -->
 * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
 * ```
 *
 * Now, when the view changes (once the link is clicked), ngAnimate will examine the
 * HTML contents to see if there is a match reference between any components in the view
 * that is leaving and the view that is entering. It will scan both the view which is being
 * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
 * contain a matching ref value.
 *
 * The two images match since they share the same ref value. ngAnimate will now create a
 * transport element (which is a clone of the first image element) and it will then attempt
 * to animate to the position of the second image element in the next view. For the animation to
 * work a special CSS class called `ng-anchor` will be added to the transported element.
 *
 * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
 * ngAnimate will handle the entire transition for us as well as the addition and removal of
 * any changes of CSS classes between the elements:
 *
 * ```css
 * .banner.ng-anchor {
 *   /&#42; this animation will last for 1 second since there are
 *          two phases to the animation (an `in` and an `out` phase) &#42;/
 *   transition:0.5s linear all;
 * }
 * ```
 *
 * We also **must** include animations for the views that are being entered and removed
 * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
 *
 * ```css
 * .view-animation.ng-enter, .view-animation.ng-leave {
 *   transition:0.5s linear all;
 *   position:fixed;
 *   left:0;
 *   top:0;
 *   width:100%;
 * }
 * .view-animation.ng-enter {
 *   transform:translateX(100%);
 * }
 * .view-animation.ng-leave,
 * .view-animation.ng-enter.ng-enter-active {
 *   transform:translateX(0%);
 * }
 * .view-animation.ng-leave.ng-leave-active {
 *   transform:translateX(-100%);
 * }
 * ```
 *
 * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
 * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
 * from its origin. Once that animation is over then the `in` stage occurs which animates the
 * element to its destination. The reason why there are two animations is to give enough time
 * for the enter animation on the new element to be ready.
 *
 * The example above sets up a transition for both the in and out phases, but we can also target the out or
 * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
 *
 * ```css
 * .banner.ng-anchor-out {
 *   transition: 0.5s linear all;
 *
 *   /&#42; the scale will be applied during the out animation,
 *          but will be animated away when the in animation runs &#42;/
 *   transform: scale(1.2);
 * }
 *
 * .banner.ng-anchor-in {
 *   transition: 1s linear all;
 * }
 * ```
 *
 *
 *
 *

 *
 * ### How is the element transported?
 *
 * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
 * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
 * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
 * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
 * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
 * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
 * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
 * will become visible since the shim class will be removed.
 *
 * ### How is the morphing handled?
 *
 * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
 * what CSS classes differ between the starting element and the destination element. These different CSS classes
 * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
 * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
 * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
 * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
 * the cloned element is placed inside of root element which is likely close to the body element).
 *
 * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
 *
 *
 * ## Using $animate in your directive code
 *
 * So far we've explored how to feed in animations into an AngularJS application, but how do we trigger animations within our own directives in our application?
 * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
 * imagine we have a greeting box that shows and hides itself when the data changes
 *
 * ```html
 * <greeting-box active="onOrOff">Hi there</greeting-box>
 * ```
 *
 * ```js
 * ngModule.directive('greetingBox', ['$animate', function($animate) {
 *   return function(scope, element, attrs) {
 *     attrs.$observe('active', function(value) {
 *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
 *     });
 *   });
 * }]);
 * ```
 *
 * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
 * in our HTML code then we can trigger a CSS or JS animation to happen.
 *
 * ```css
 * /&#42; normally we would create a CSS class to reference on the element &#42;/
 * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
 * ```
 *
 * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
 * possible be sure to visit the {@link ng.$animate $animate service API page}.
 *
 *
 * ## Callbacks and Promises
 *
 * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
 * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
 * ended by chaining onto the returned promise that animation method returns.
 *
 * ```js
 * // somewhere within the depths of the directive
 * $animate.enter(element, parent).then(function() {
 *   //the animation has completed
 * });
 * ```
 *
 * (Note that earlier versions of AngularJS prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
 * anymore.)
 *
 * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
 * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
 * routing controller to hook into that:
 *
 * ```js
 * ngModule.controller('HomePageController', ['$animate', function($animate) {
 *   $animate.on('enter', ngViewElement, function(element) {
 *     // the animation for this route has completed
 *   }]);
 * }])
 * ```
 *
 * (Note that you will need to trigger a digest within the callback to get AngularJS to notice any scope-related changes.)
