This model generates the final state for hadron inelastic
scattering using leading particle biasing techniques. For details,
see the chapter on the Leading Particle Bias Model (G4Mars5GeV)
in the Geant4 Physics Reference Manual.
Invocation:
G4Mars5GeV* leadModel = new G4Mars5GeV();
This model may be registered to the inelastic process corresponding
to any of the particles listed below, for example the proton:
G4ProtonInelasticProcess* inelProcess = new G4ProtonInelasticProcess();
inelProcess->RegisterMe(leadModel);
processManager->AddDiscreteProcess(inelProcess);
