//    Class used in the definition of the optical photons source
//    A plane, circular source is used. Depending on the source position, optical
//    photons may reach the UVscope directly or after reflection. By default direct
//    incidence is used. The source parameters can be set directly in this class
//    or through the GeneralParticleSource  messenger class.
