 *
 * Example usage in case of protons:
 * @code
 * G4InclCascadeInterface* inclModel = new G4InclCascadeInterface;
 * inclModel -> SetMinEnergy(0.0 * MeV); // Set the energy limits
 * inclModel -> SetMaxEnergy(3.0 * GeV);

 * protonInelasticProcess -> RegisterMe(inclModel);
 * protonInelasticProcess -> AddDataSet(protonInelasticCrossSection);
 *
 * particle = G4Proton::Proton();
 * processManager = particle -> GetProcessManager();
 * processManager -> AddDiscreteProcess(protonInelasticProcess);
 * @endcode
 * The same setup procedure is needed for neutron and pion inelastic processes
 * as well.
