Customized ListControl
This sample shows a customized ListControl.
Therfore the DefListPainter was subclassed and the new AppSimpleListPainter was registerd
in the doCreatePainter method of the AppPainterfactory.

Note: If you can see in the doCreatePainter method all SimpleListControl will use the new Painter.
If you want more control and render different ListControls in differnt ways, you can subclass the
SimpleListControl class and register for each sublass a different new ListPainter. Therefore use the
existing source code and modify it to your own needs.
