* Der GroupManager horcht an der starform, ob FormComponents eingefuegt oder entfernt
* werden. Zusaetzlich horcht er bei den FormComponents an den Properties
* "Name" und "TabIndex". Mit diesen Infos aktualisiert er seine Gruppen.
*
* Der GroupManager verwaltet eine Gruppe, in der alle Controls nach TabIndex
* geordnet sind, und ein Array von Gruppen, in dem jede FormComponent noch
* einmal einer Gruppe dem Namen nach zugeordnet wird.
* Die einzelnen Gruppen werden ueber eine Map aktiviert, wenn sie mehr als
* ein Element besitzen.
*
* Die Gruppen verwalten intern die FormComponents in zwei Arrays. In dem
* GroupCompArray werden die Components nach TabIndex und Einfuegepostion
* sortiert. Da auf dieses Array ueber die FormComponent zugegriffen
* wird, gibt es noch das GroupCompAccessArray, in dem die FormComponents
* nach ihrer Speicheradresse sortiert sind. Jedes Element des
* GroupCompAccessArrays ist mit einem Element des GroupCompArrays verpointert.
