// This class provides all the physic models that can be activated inside ML2;
// Each model can be setted via macro commands;
// Inside ML2 the models can be activate with three different complementar methods:
//
// 1. Use of the *Packages*.
//    Packages (that are contained inside the
//    Geant4 distribution at $G4INSTALL/source/physics_lists/lists) provide a full set
//    of models (both electromagnetic and hadronic).
//    The User can use this method simply add the line /physic/addPackage <nameOfPackage>
//    in his/her macro file. No other action is required.
//    For ML2 applications we suggest the use of the QGSP_BIC package
//    for proton beams. The same can be used
//    also for ligth ion beam.
//   
//
// 2. Use of the *Physic Lists*.
//    Physic lists are also already ready to use inside the Geant4 distribution
//    ($G4INSTALL/source/physics_lists/builders). To use them the simple
//    /physic/addPhysics <nameOfPhysicList> command must be used in the macro.
//    In ML2 we provide physics list to activate Electromagnetic,
//    Hadronic elastic and Hadronic inelastic models.
//
//    For ML2 we suggest the use of:
//
//    /physic/addPhysic/emstandard_option3 (electromagnetic model)
//    /physic/addPhysic/elastic (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 
//
