//------------------ G4GammaConversion physics process------------------------
//                   by Michel Maire, 24 May 1996
//
// 11-06-96, Added GetRandomAtom() method and new data member
//           for cumulative total cross section, by M.Maire
// 21-06-96, SetCuts inplementation, M.Maire
// 16-09-96, Dynamical array PartialSumSigma, M.Maire
// 14-01-97, crossection table + meanfreepath table.
//           PartialSumSigma removed, M.Maire
// 14-03-97, new physics scheme for geant4alpha, M.Maire
// 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: "conv"
// 20-09-01, DoIt: fminimalEnergy = 1*eV (mma)
// 01-10-01, come back to BuildPhysicsTable(const G4ParticleDefinition&)
// 13-08-04, suppress .icc file
//           public ComputeCrossSectionPerAtom() and ComputeMeanFreePath() (mma)
// 09-11-04, Remove Retrieve tables (V.Ivantchenko)
// 19-04-05, Redesign - use G4VEmProcess interface (V.Ivantchenko)
// 04-05-05, Make class to be default (V.Ivanchenko)
// 09-08-06, add SetModel(G4VEmModel*) (mma)
// 12-09-06, move SetModel(G4VEmModel*) in G4VEmProcess (mma)
