/*
 *	CBaseMoniker is a base implementation class that does the
 *	following:
 *	
 *	1.	It implements QueryInterface, AddRef, and IsDirty,
 *		since these all have the same implementation for all the moniker
 *		classes defined here.
 *	
 *	2.	It returns error messages for other methods.  Normally
 *		these will be replaced by real implementations in the
 *		derived classes, but in some cases, AntiMonikers, for
 *		instance, it allows us to declare and write only those
 *		methods with meaningful implementations.  Methods such as
 *		BindToObject for antimonikers will inherit the error code
 *		form the base implementation.
