28 // 20100506 M. Kelsey -- Move functionality of G4CascadeChannel here,
29 // use as base class to G4CascadeFunctions<T>.
30 // 20100512 M. Kelsey -- Make this templated on energy and multiplicity
31 // binning, as base to new sampler.
32 // 20100803 M. Kelsey -- Add print function for debugging.
33 // 20110923 M. Kelsey -- Add optional ostream& argument to print()
