 * vtkSubsetInclusionLattice in QWidget. Each top-level nodes in the SIL,
 * is shown as a Tab with the subtree under those shown in  separate pqTreeView
 * instances under each of the tabs.
 *
 * While it can work with any QAbstractItemModel, pqSubsetInclusionLatticeWidget
 * is intended to be used with pqSubsetInclusionLatticeTreeModel.
