                              ---------------

 Provied a base class where a TCustomMaskedit (derived) control is
 grouped inside a TCustomControl with a TControl derived class.

 The objective of this baseclass is to forward all relevant methods and
 properties of TCustomMaskEdit.
 Grouping the controls inside a TCustomControl is done, so that the
 resulting control will properly align and anchor.
