// This class provides all the physic models that can be activated inside Hadrontherapy;
// Each model can be setted via macro commands;
// Inside Hadrontherapy the models can be activate with three different complementar methods:
//
// 1. Use of the *Packages*.
//    Packages (that are contained inside the
//    Geant4 distribution at $G4INSTALL/source/physics_lists/lists) provide a full set
//    of models (both electromagnetic and hadronic).
//    The User can use this method simply add the line /physic/addPackage <nameOfPackage>
//    in his/her macro file. No other action is required.
//    For Hadrontherapy applications we suggest the use of the QGSP_BIC package
//    for proton beams. The same can be used
//    also for ligth ion beam.
//    Example of use of package can be found in the packageQGSP_BIC.mac file.
//
// 2. Use of the *Physic Lists*.
//    Physic lists are also already ready to use inside the Geant4 distribution
//    ($G4INSTALL/source/physics_lists/builders). To use them the simple
//    /physic/addPhysics <nameOfPhysicList> command must be used in the macro.
//    In Hadrontherapy we provide physics list to activate Electromagnetic,
//    Hadronic elastic and Hadronic inelastic models.
//
//    For Hadrontherapy we suggest the use of:
//
//    /physic/addPhysic/emstandard_option3 (electromagnetic model)
//    /physic/addPhysic/QElastic (hadronic elastic model)
//    /physic/addPhysic/binary (hadronic inelastic models for proton and neutrons)
//    /physic/addPhysic/binary_ion (hadronic inelastic models for ions)
//
//    Example of the use of physics lists can be found in the macro files included in the
//    'macro' folder .
//
// 3. Use of a *local* physics. In this case the models are implemented in local files
//    contained in the Hadrontherapy folder. The use of local physic is recommended
//    to more expert Users.
//    We provide as local, only the LocalStandardICRU73EmPhysic.cc (an Elecromagnetic
//    implementation containing the new ICRU73 data table for ions stopping powers)
//    and the LocalIonIonInelasticPhysic.cc (physic list to use for the ion-ion interaction
//    case)
//    The *local* physics can be activated with the same /physic/addPhysic <nameOfPhysic> command;
//
//    While Packages approch must be used exclusively, Physics List and Local physics can
//    be activated, if necessary, contemporaneously in the same simulation run.
//
//    AT MOMENT, IF ACCURATE RESULTS ARE NEDED, WE STRONGLY RECOMMEND THE USE OF THE MACROS:
//    proton_therapy.mac: use of the built-in Geant4 physics list for proton beams)
//    ion_therapy.mac   : use of mixed combination of native Geant4 physic lists
//                        and local physic for ion-ion enelastic processes)
