//      History: 
//	 	1 July 2009 creation by L. Desorgher based on a modification of G4Alpha 		
//
//-------------------------------------------------------------
//	Documentation:
//		Adjoint particles are used in Reverse/Adjoint Monte Carlo simulations. New adjoint 
//		processes act on adjoint particles when they are  tracked backward in the geometry. 
//		The use of adjoint particles instead of "normal" particles during a reverse simulation 
//		is based on an idea of M. Asai.
