 * @class   vtkSMNamedPropertyIterator
 * @brief   iterates over a subset of a proxy's properties
 *
 *
 * vtkSMNamedPropertyIterator can be used to iterate over a subset of a proxy's
 * properties. The subset is defined through a list of strings naming properties.
 * The properties of the root proxies as well as sub-proxies are  included in the
 * iteration. For sub-proxies, only exposed properties are iterated over.
