// Short comment: This is a physics list of only one model G4QInelastic for
// all hadron-nuclear interactions at all energies. There is no model- or
// process-mixing, while it is possible to merge (G4QProcessMixer) the G4_HP
// processes at low energies if the G4QInelastic, which includes all necessary
// nA inelastic processes, is found to be not saficient for some applications.
// In this particular builder the G4QInelastic process is attached to all
// hadrons other than nucleons or pi and K-mesons. Previously it could be done
// only using the LHEP parameterized package or in a temporary form by the
// QGSC model conditionally extended (just not crashing) to low energies.
// *** Important *** As the CHIPS treatment of all hadrons is the same, and
// very simple, this builder with time can be not used in the CHIPS physics list
