 *  Configuration Panel Interpreter default implementation.
 *  The interface that any configuration/preference dialog uses
 *  to modify its data and get its particular gui widges (IPanel).
 *
 *  Derived classes with this interface mediate between IConfigPanel 
 *  and classes with the CSettingsSet base class, in the context of a
 *  CConfigDlg.
