// 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
// 12.02.2013 (V.Ivanchenko) added virtual method GetLifeTime,
//                          enumerator G4EvaporationChannelType,
//                          which is defined in constructor of the class
//
