// Hadronic Process: Nuclear De-excitations
// by V. Lara (May 1998)
//
// Modifications:
// 30 June 1998 by V. Lara:
//      -Using G4ParticleTable and therefore G4IonTable
//       it can return all kind of fragments produced in 
//       deexcitation
//      -It uses default algorithms for:
//              Evaporation: G4StatEvaporation
//              MultiFragmentation: G4DummyMF (a dummy one)
//              Fermi Breakup model: G4StatFermiBreakUp
//
// 03 September 2008 by J. M. Quesada for external choice of inverse 
//    cross section option
// 06 September 2008 JMQ Also external choices have been added for 
//    superimposed Coulomb barrier (if useSICBis set true, by default is false)  
// 23 January 2012 by V.Ivanchenko remove obsolete data members; added access
//    methods to deexcitation components
//
