//
//---------------------------------------------------------------------------
//
// ClassName: G4CRMCModel
//
// Author:    2018 Alberto Ribon
//
// Geant4 wrapper hadronic model around CRMC.
// By changing a single number (model) it is possible to use one of the
// following 4 CRMC generators:  0 :  EPOS LHC
//                               1 :  EPOS 1.99
//                               6 :  SIBYLL 2.3c
//                              12 :  DPMJET 3
//
// We are pleased to acknowledge the contribution of Andrii Tykhonov
// (Universite' de Geneve, and member of the DAMPE Collaboration) 
// who made the first prototype interface between Geant4 and CRMC,
// and shared his expertise and implementation with us. 
//
// Modified:
