Remarks:

	It cannot be put into a library because of ATL code.

Revision History:

    Name        Date        Comments
    aoltean     09/01/1999  Created
    aoltean     09/09/1999  dss -> vss
	aoltean		09/13/1999	Moved to inc. Renamed to copy.inl
	aoltean		09/20/1999	Adding methods for creating the snapshot, snapshot set,
							provider and volume property structures.
							Also VSS_OBJECT_PROP_Manager renamed to VSS_OBJECT_PROP_Manager.
