// 20100114  M. Kelsey -- Remove G4CascadeMomentum, use G4LorentzVector directly
// 20100409  M. Kelsey -- Drop unused string argument from ctors.
// 20100429  M. Kelsey -- Change "photon()" to "isPhoton()", use enum names
// 20100914  M. Kelsey -- Move printout to .cc file
// 20100915  M. Kelsey -- Add hyperon() identification function, ctor for
//      G4DynamicParticle
// 20110117  M. Kelsey -- Add antinucleon() and antibaryon() flag
// 20110127  M. Kelsey -- Drop generation.
// 20110214  M. Kelsey -- Replace integer "model" with enum
// 20110321  M. Kelsey -- Fix getStrangeness() to return int
// 20110721  M. Kelsey -- Add constructors to take G4ParticleDefinition as
//      input instead of type code, to allow pass-through of unusable
//      particles during rescattering.  Modify ctors to pass model to
//      base ctor.
// 20110801  M. Kelsey -- Add fill() functions to replicate ctors, allowing
//      reuse of objects as buffers; c.f. G4InuclNuclei.
// 20110922  M. Kelsey -- Add stream argument to printParticle() => print()
// 20120608  M. Kelsey -- Fix variable-name "shadowing" compiler warnings.
