PURPOSE: Immersion Foundation Classes Base Effect
STARTED: Oct.10.97
NOTES/REVISIONS:
Mar.02.99 jrm (Jeff Mallett): Force-->Feel renaming
Mar.02.99 jrm: Added GetIsCompatibleGUID and feel_to_DI_GUID
Mar.15.99 jrm: __declspec(dllimport/dllexport) the whole class
Nov.15.99 efw (Evan Wies): Converted to IFC
