  /**
    \class GlobalPhysicsList
    \brief G4VUserPhysicsList to aggregate physics lists to be used by multiple Geant4 modules in one offline session.

    This physics list is only a container. It is an aggregation of
    lists where it is expected there will be a default list that
    provides most of the processes and particles and other lists that
    can potentially add processes that are used in particular
    modules. Currently the only default physics list is
    DefaultPhysicsList.

    In order to run a module with a customized physics list, one only
    needs to provide a class that inherits from G4VUserPhysicsList and
    register it using the RegisterPhysics method. This list (and none
    of the geant4 tools for that matter) will check the consistency of
    the lists created. It is the responsibility of the module
    developers to keep track of that.
