A data model for a combo box. This interface extends 
ListModel
 and adds the concept of a selected item. The selected item is generally
 the item which is visible in the combo box display area.
 
 The selected item may not necessarily be managed by the underlying
 ListModel. This disjoint behavior allows for the temporary
 storage and retrieval of a selected item in the model.
