// Short description: In fact this is the definition of the Hadronic Inelastic
// physics. The definition of the Hadronic Elastic physics one can find in the
// G4HadronQElasticPhysics, which is stable (the same for all physics lists).
// The only "unstable" part of the physics is the Hadronic Inelastic physics,
// which is usually composed of the wixing of the High Energy Inelastic Model
// (HEIM) and the Low Energy Inelastic Model (LEIM), which are applied only for
// some hadrons (mostly nucleons and pi-mesons), above the LHEP model, which
// usually covers all particles (but for Sigma_0 ?) and sometimes covers the
// "hole" between the LEIM and HIME at intermediate energies. The name of the
// Physics list is usually have a form HEIM_LEIM and the inelastic interactions
// are defined in the HadronicPhysicsHEIM_LEIM class. So in this particular
// physics list the low energy model is CHIPS (G4QCollision process) and the
// high energy model is QGSC (QGS with the Energy Flow interface to CHIPS),
// which are in terms of the energy boundary are mixed not on the model level,
// but on the process level (G4DiscProcessMixer class). The LHEP is completely
// excluded from this physics list, because the MiscLHEP is substituted by the
// MiscQGSC class (QGS with the Energy Flow interface to CHIPS), covering all
// particles, which are not N, pi, or K, defined by the separate builders.
