 * COMMENTARY   : This class allow you creating a menu bar using path for menus & actions, ie :
	For creating action File->Open simply use :
		class->menu( "mFile", tr( "&File" ) );
		class->action( "mFile/aOpen" );
	For creating menu File->Recents simply use :
		class->menu( "mFile", tr( "&File" ) );
		class->menu( "mFile/mRecents", tr( "&Recents" ) );
	This class use some modified code ( group members ) from Trolltech SA (c) QSettings.
