// G4 Process: Gheisha High Energy Collision model.
// This includes the high energy cascading model, the two-body-resonance model
// and the low energy two-body model. Not included are the low energy stuff like
// nuclear reactions, nuclear fission without any cascading and all processes for
// particles at rest.  
// First work done by J.L.Chuma and F.W.Jones, TRIUMF, June 96.
