// Hadronic Process: Nuclear Preequilibrium
// by V. Lara 
//
// Modif (03 September 2008) by J. M. Quesada for external choice of inverse 
// cross section option
// JMQ (06 September 2008) Also external choice has been added for:
//                      - superimposed Coulomb barrier (if useSICB=true) 
// 20.08.2010 V.Ivanchenko added G4Pow and G4PreCompoundParameters pointers
//                         use int Z and A and cleanup; 
//                         inline methods moved from icc file to hh
