* The GroupManager listens at the StarForm for FormComponent insertion and removal as well as
* its properties "Name" and "TabIndex" and updates its Group using this information.
*
* The GroupManager manages a Group in which all Controls are sorted by TabIndex.
* It also manages an array of Groups, in which each FormComponent is assigned a
* Group according to its name.
* Each Group is activated using a Map, if they contain more than one element.
*
* The Groups manage the FormComponents internally using two arrays.
* In the GroupCompArray the Components are sorted by TabIndex and insertion position.
* Because this array is accessed via the FormComponent, we also have the GroupCompAccessArray
* in which the FormComponents are sorted by their storage address.
* Every element of the GroupCompArray has a pointer to the GroupCompArray.
