/**
 * The ObservableCollection interface acts as a super interface for all the collection
 * objects in the Observable framework.  It requires its implementors to 
 * store its own listeners.
 * <p>Although the Map and Bag are technically according to Sun not a Collection, they
 * are used through the Collections framework as if they are.  This inconsistency is
 * carried through to this package, as a Map and Bag are treated as a normal collection
 * for ease of use and consistency throughout the framework.
