//  FUNCTION: CShellExt::Initialize(LPCITEMIDLIST, LPDATAOBJECT, HKEY)
//
//  PURPOSE: Called by the shell when initializing a context menu or property
//           sheet extension.
//
//  PARAMETERS:
//    pIDFolder - Specifies the parent folder
//    pDataObj  - Spefifies the set of items selected in that folder.
//    hRegKey   - Specifies the type of the focused item in the selection.
//
//  RETURN VALUE:
//
//    NOERROR in all cases.
//
//  COMMENTS:   Note that at the time this function is called, we don't know 
//              (or care) what type of shell extension is being initialized.  
//              It could be a context menu or a property sheet.
