// CHANGE HISTORY
// --------------
//
//
// Version 1.0, 05/02/2004, Fan Lei, Created.
// Based on the G4GeneralParticleSource class in Geant4 v6.0

//
// Class Description:
//
// Special random number generator used by G4GeneralParticleSource to allow
// biasing applied at the lowest level for all distributions.
//

// G4SPSRandomGenerator ()
// Constructor: Initializes variables
//
// ~G4SPSRandomGenerator ()
// Destructor:
