0003 G4CXOpticks, Replaced G4Opticks
0004 =========================================================
0005
0006 * KEEP THIS MINIMAL : PROVIDING TOP LEVEL INTERFACE AND COORDINARION
0007 * EVERYTHING THAT CAN BE IMPLEMENTED AT LOWER LEVELS SHOULD BE IMPLEMENTED AT LOWER LEVELS
0008
0009   * IN THIS REGARD THE THREE PRIMARY METHODS simulate/simtrace/render ALL NEED OVERHAUL
0010     TO INSTEAD RELAY ON CSGOptiX LEVEL
0011
0012 HMM: instanciating CSGOptiX instanciates QSim for raygenmode other than zero
0013 and that needs the upload of QSim components first ?
