// 20100114  M. Kelsey -- Remove G4CascadeMomentum, use G4LorentzVector directly
// 20100407  M. Kelsey -- Replace ::resize(0) with ::clear()
// 20100409  M. Kelsey -- Move function code to .cc files, not inlinable
// 20100418  M. Kelsey -- Add function to boost output lists to lab frame
// 20100520  M. Kelsey -- Add function to rotate Z axis, from G4Casc.Interface
// 20100620  M. Kelsey -- Add setVerboseLevel() function
// 20100715  M. Kelsey -- Add total charge and baryon number functions, and a
//      combined "add()" function to put two of these together.
// 20100716  M. Kelsey -- Add interface to handle G4CascadParticles
// 20100924  M. Kelsey -- Use "OutgoingNuclei" name consistently, replacing
//      old "TargetFragment".  Add new (reusable) G4Fragment buffer 
//      and access functions for initial post-cascade processing.
//      Move implementation of add() to .cc file.
// 20100925  M. Kelsey -- Add function to process G4ReactionProduct list
