/*
 *	OLE 2 default object handler
 *
 *      Copyright 1999  Francis Beaudet
 *
 * NOTES:
 *    The OLE2 default object handler supports a whole whack of
 *    interfaces including:
 *       IOleObject, IDataObject, IPersistStorage, IViewObject2,
 *       IRunnableObject, IOleCache2, IOleCacheControl and much more.
 *
 *    All the implementation details are taken from: Inside OLE
 *    second edition by Kraig Brockschmidt,
 *
 * TODO
 * - This implementation of the default handler does not launch the
 *   server in the DoVerb, Update, GetData, GetDataHere and Run
 *   methods. When it is fixed to do so, all the methods will have
 *   to be  revisited to allow delegating to the running object
 *
 * - All methods in the class that use the class ID should be
 *   aware that it is possible for a class to be treated as
 *   another one and go into emulation mode. Nothing has been
 *   done in this area.
 *
 * - Some functions still return E_NOTIMPL they have to be 
 *   implemented. Most of those are related to the running of the
 *   actual server.
 *
 * - All the methods related to notification and advise sinks are
 *   in place but no notifications are sent to the sinks yet.
