*
* 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.
