//               -April  2008 First implementation  by L. Desorgher

//      Documentation:
//              Stacking action used in the adjoint simulation. It is responsible to kill a primary forward particle before it is traked  in the forwrad phase 
//              if the last adjoint particle did not reach the adjoint surface. Was needed for the new design where the G4AdjointSimManager is no more an extension
//              of the G4RunManager. If the primary particles is not killed before being tracked in the sensitive geometry, the User Stacking action 
//              can be used duiring the forward phase if specified by the method  G4AdjointSimManager::UseUserStackingAction(Bool). 
//
