// Revision 1.7  2017/05/03 15:54:21  akio
// added gain scaling when attenuation was on during geant simulation

// Revision 1.6  2015/09/29 16:28:58  akio
// setFmsZS(int v) and if ADC<v, drop the hit (default=2)
// adding poisson distribution for FPS, with setFpsNPhotonPerMIP(float v)
//  (default=0 for now, which turns this off. It should be around 100?)

// Revision 1.5  2015/09/18 18:44:28  akio
// uses StEnumeration
