//
// by V. Lara
//
// Class Description
// Model implementation for pre-equilibrium decay models in geant4. 
// To be used in your physics list, in case you neeed this kind of physics.
// Can be used as a stand-allone model, but also in conjunction with an intra-nuclear
// transport, or any of the string-parton models.
// Class Description - End
//
// Modified:
// 03.09.2008 J.M.Quesada added external choice of inverse 
//            cross section option.(default OPTxs=3)
// 06.09.2008 J.M.Quesada external choices have been added for:
//                - superimposed Coulomb barrier (if useSICB=true, default false) 
//                - "never go back"  hipothesis (if useNGB=true, default false) 
//                - soft cutoff from preeq. to equlibrium (if useSCO=true, default false)
//                - CEM transition probabilities (if useCEMtr=true)
// 30.10.2009 J.M.Quesada CEM transition probabilities are set as default
// 20.08.2010 V.Ivanchenko Cleanup of the code - changed data members and inline methods
