* @short Filter model which hides/shows entites marked as trash

* Filter model which either hides all entities marked as trash, or the ones not marked.
* Subentities of collections marked as trash are also shown in the trash.

* The Base model must be an EntityTreeModel and the EntityDeletedAttribute must be available.

*
* @code
*
* ChangeRecorder *monitor = new Akonadi::ChangeRecorder( this );
* monitor->itemFetchScope().fetchAttribute<Akonadi::EntityDisplayAttribute>(true);

* Akonadi::EntityTreeModel *sourcemodel = new Akonadi::EntityTreeModel(monitor, this);
