// Modified for LArG4 by Ben Jones, MIT, Nov 2012
//
// Thisclass is based upon thedefaultGeant4 optical physics constructor.
// However, forfast optical physics inLArSoft:
//
// - The default geant4 scintillation process is swapped for the LArG4 fast
//     scintillation process
//
// - Cerenkov light (still slow) can beenabledor disabled as required
//
// - The default geant4reflection 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.
