//------------------ G4ComptonScattering physics process -----------------------
//                   by Michel Maire, April 1996
//
// 10-06-96, updated by M.Maire
// 21-06-96, SetCuts implementation, M.Maire
// 06-01-97, crossection table + meanfreepath table, M.Maire
// 17-02-97, New Physics scheme
// 25-02-97, GetMeanFreePath() now is public function
// 12-03-97, new physics scheme again
// 13-08-98, new methods SetBining()  PrintInfo()
// 03-08-01, new methods Store/Retrieve PhysicsTable (mma)
// 06-08-01, BuildThePhysicsTable() called from constructor (mma)
// 19-09-01, come back to previous ProcessName "compt"
// 20-09-01, DoIt: fminimalEnergy = 1*eV (mma)
// 01-10-01, come back to BuildPhysicsTable(const G4ParticleDefinition&)
// 13-08-04, suppress icc file; make public ComputeCrossSectionPerAtom()   (mma)
// 09-11-04, Remove Retrieve tables (V.Ivantchenko)
// 15-03-05, Redesign - use G4VEmProcess interface (V.Ivantchenko)
// 04-05-05, Make class to be default (V.Ivanchenko)
// 09-09-06, modify SetModel(G4VEmModel*) (mma)
// 12-09-06, move SetModel(G4VEmModel*) in G4VEmProcess (mma)
