* OLE 2 Data cache

* Copyright 1999 Francis Beaudet
*
* NOTES:
* The OLE2 data cache supports a whole whack of
* interfaces including:
* IDataObject, IPersistStorage, IViewObject2,
* IOleCache2 and IOleCacheControl.
*
* All the implementation details are taken from: Inside OLE
* second edition by Kraig Brockschmidt,
*
* TODO
* Allmost everything is to be done. Handling the cached data,
* handling the representations, drawing the representations of
* the cached data... yada yada.
