// Modified for LArG4 by Ben Jones, MIT, Sept 2009
//
// This class is based upon the default Geant4 optical physics constructor.
// However, for optical physics in LArSoft:
//
// - Cerenkov light can be enabled or disabled as required
//
// - The default geant4 reflection process is swapped for a simpler
//     custom boundary process in LArG4
//
// Parameters relating to the physics in this constructor can be set
// in the Utilities/LArParameters service.
//
