//  $HISTORY:
//
//  16 Jun 1996 :   1.0 : first public Release
//
//  27 Jul 1996 :   1.1 : Bug Fixes:
//                        - MUIGroupH::MUIGroupH();
//                          MUIGroupV::MUIGroupV();
//                          MUIGroupCol::MUIGroupCol(const LONG);
//                          MUIGroupRow::MUIGroupRow(const LONG);
//                          Bei diesen Konstruktoren war ein Fehler der dazu führte, daß
//                          die Methode Create() die falschen Parameter bekam.
//                        Änderungen:
//                        - Add(), Rem()
//                          Der Parameter wurde von 'MUIGroup &' auf 'Object *' geändert.
//
//  02 Sep 1996 :   1.2 : Bug Fixes:
//                        - MUIGroupH::MUIGroupH();
//                          MUIGroupV::MUIGroupV();
//                          MUIGroupCol::MUIGroupCol(const LONG);
//                          MUIGroupRow::MUIGroupRow(const LONG);
//                          Die Konstruktoren mit Parameter 'struct TagItem *' und NULL
//                          als Wert hatten TAG_MORE mit NULL als Zeiger.
//                        Neu:
//                        - Die Methode Sort() wurde für MUI 3.6 hinzugefügt.
//                        - ClassNum() für Exception-Handling.
//                        Änderungen:
//                        - Parameter des Copy-Konstruktor als 'const'-Parameter definiert
