//  Function:   InsertServerMenus
//
//  Synopsis:   Inserts the objects menus into a shared menu after
//              the top-level application has inserted its menus
//
//  Arguments:  [hmenuShared] -- the shared menu to recieve the objects menus
//              [hmenuObject] -- all of the objects menus
//              [lpmgw] -- menu group widths indicating where the menus
//                          should be inserted
//
//  Returns:    Success if the menus were merged successfully
//
//  Notes:      The function does most of the shared menu work
//              by the object between the IOleInPlaceFrame::InsertMenus and
//              IOleInPlaceFrame::SetMenu method calls.
