Funktionsweise GroupManager:
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.
