0005 // Description:
0006 // this is an EvtRandomEngine
0007 // It is used as an interface of the random number engine provided
0008 // by the random number generator service and EvtGen
0009 // Its "random()" method uses the "Flat()" method of the CLHEP::HepRandomEngine
0010 // provided by the Random Number Generator Service
