  21  * NOTES:
  22  *    The OLE2 default object handler supports a whole whack of
  23  *    interfaces including:
  24  *       IOleObject, IDataObject, IPersistStorage, IViewObject2,
  25  *       IRunnableObject, IOleCache2, IOleCacheControl and much more.
  26  *
  27  *    All the implementation details are taken from: Inside OLE
  28  *    second edition by Kraig Brockschmidt,
  29  *
  30  * TODO
  31  * - This implementation of the default handler does not launch the
  32  *   server in the DoVerb, Update, GetData, GetDataHere and Run
  33  *   methods. When it is fixed to do so, all the methods will have
  34  *   to be  revisited to allow delegating to the running object
  35  *
  36  * - All methods in the class that use the class ID should be
  37  *   aware that it is possible for a class to be treated as
  38  *   another one and go into emulation mode. Nothing has been
  39  *   done in this area.
  40  *
  41  * - Some functions still return E_NOTIMPL they have to be
  42  *   implemented. Most of those are related to the running of the
  43  *   actual server.
  44  *
  45  * - All the methods related to notification and advise sinks are
  46  *   in place but no notifications are sent to the sinks yet.
