// Hadronic Process: Inelastic Interaction 
// This class is an abstract base class, since the pure virtual

// original by H.P. Wellisch
// Modified by J.L. Chuma, TRIUMF, 22-Nov-1996
// Modified by J.L. Chuma  27-Mar-1997
// Modified by J.L. Chuma  30-Apr-1997
// Modified by J.L. Chuma  05-Aug-1997  to pass the original incident particle to
//                                      CalculateMomenta
// Modified by J.L. Chuma  05-Jun-1998  to include quasiElastic flag to allow for
//                                      TwoBody to be called directly, bypassing
//                                      TwoCluster, and allowing TwoCluster to be
//                                      called with no secondaries
// 23-Jan-2009 V.Ivanchenko move constructor and destructor to the body
// 29-Aug-2009 V.Ivanchenko moveded G4ReactionDynamics instance from the based class
