The controller configuration window can be used to set
the controller for each group.
Only controllers which belong to 'GROUP' are listed on the left screen part.
To edit a controller, it must be selected in the list.
After having changed a field (script1, script2 or comment), it must be validated by clicking on the appropriate button.
The 'add' button can be used to create a new controller. The controller mask must be provided at this time, and will not be editable anymore. In order to change a controller mask, the controller must be deleted and re-created with the correct mask.
