//      History: 
//    1st March 2007 creation by L. Desorgher based on a modification of G4Gamma

//      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
