//      class for Decay Channels of Hadrons in CHIPS Model
// -------------------------------------------------------------------
// Short description: In the CHIPS World the particles (G4QParticle)
// are defined. For unstable particles there is a G4QDecayChannelVector
// which describes different channels of decay for the particular
// particle. So the G4QDecayChannel class is the class for the description
// of such a decay channel in two or three particles (the secondaries can
// be unstable too and have firther decay).
