//
// Physics models in IORT, following the Geant4 organisation, can be definided using three different approaches:
// 1. Activating one of the 'Reference Physics Lists' that are already prepared by
//    the Geant4 Collaboration and are contained in the $G4INSTALL/source/physics_lists/lists folder
//    The 'Reference Physics Lists' can be activated setting a specific enviroment variable to the name
//    of the physics. For example if the QGSP_BIC Reference Physics Lists must be activated the User 
//    must set export PHYSLIST=QGSP_BIC (or setenv PHYSLIST QGSP_BIC).
//    A 'Reference Physics Lists' contains all the physics process necessary to a particle transport
//    If the User set the PHYSLIST variable IORT will start with the defaultMacroWithReferencePhysicsList.mac
//    macro. See this macro file for more details
//
// 2. Activating the 'Builders' already prepared by
//    the Geant4 Collaboration and contained in the $G4INSTALL/source/physics_lists/builder folder.
//    Each builder is specific of a given model. There are builders for the electromagnetic processes, for the
//    hadronic one, etc.
//    If the PHYSLIST variable is not defined IORT starts with the defaultMacro.mac where the single builders
//    are activated for the various processes of interest.
//    Each builder is activated with the /Physics/addPhysics <nome builder> command
//
//    ******       SUGGESTED PHYSICS       *********
//
//    AT MOMENT, IF ACCURATE RESULTS ARE NEDED, WE STRONGLY RECOMMEND: 
//    1. The use of the emstandard_opt3, or
//    2. the QGSP_BIC_EMY Reference Physics Lists (define the PHYSLIST eviroment variable):
//       export PHYSLIST=QGSP_BIC_EMY
