// 	Similarly to the CIncludeView, this pane lets its superview "include" another view
//	but unlike the CIncludeView, it doesn't create the included view from a 'PPob' resource:
//	instead it searches for it in the window. This allows to create a global object like
//	a CFlexTable for instance, attach it to the window and have different tab panels share it.
//
//	The included view is put back to its original place when the CPlaceHolderView is hidden.
