/// \brief   The messenger class for the Physics List
///
/// \author p.jones22@physics.ox.ac.uk
///
/// REVISION HISTORY:\n
///     25/02/2011 : P G Jones - New File, based on PhysicsListMessenger
///                  in the Geant4.9.4 example directories.\n
///     31/08/2011 : P G Jones - Added Hadronic list selection\n
///     10/09/2012 : P G Jones - Added Cerenkov process selection\n
///     07/05/2013 : C R Jones - Major new additions to the Physics List commands\n
///     2014-08-05 : P G Jones - Switched to /rat/physics_list, added doxygen.\n
///
/// \details Introduces commands to set the Em and Hadronic Physics Lists, to
/// omit certain physics and set the secondary cut lengths.
