// Hadronic Process: Nuclear De-excitations
// by V. Lara (Oct 1998)
//
// Modified:
// 03.09.2008 (J.M.Quesada) for external choice of inverse cross section option
// 06.09.2008 (J.M.Quesada) external choices have been added for superimposed 
//                          Coulomb barrier (if useSICB is set true, by default is false) 
// 24.04.2010 (V.Ivanchenko) moved constructor and destructor to source; added two
//                          new virtual methods EmittedFragment(s) to allow more optimal
//                          work with G4Fragment objects
