// 20100112  Michael Kelsey -- Replace G4CascadeMomentum with G4LorentzVector
// 20100301  M. Kelsey -- Add function to create unphysical nuclei for use
//       as temporary final-state fragments.
// 20100319  M. Kelsey -- Remove "using" directory and unnecessary #includes.
// 20100409  M. Kelsey -- Drop unused string argument from ctors.
// 20100630  M. Kelsey -- Add excitation energy as optional public ctor arg,
//       remove excitation energy data member (part of G4Ions).  Add
//       excitation energy to "getNucleiMass()" function, move print to .cc
// 20100711  M. Kelsey -- Add optional model ID to constructors
// 20100714  M. Kelsey -- Use G4DynamicParticle::theDynamicalMass to deal with
//       excitation energy without instantianting "infinite" G4PartDefns.
// 20100719  M. Kelsey -- Move setExitationEnergy implementation to .cc file.
// 20100906  M. Kelsey -- Add fill() functions to rewrite contents
// 20100909  M. Kelsey -- Add function to discard exciton configuration
// 20100914  M. Kelsey -- Use integers for A and Z
// 20100915  M. Kelsey -- Add constructor to copy G4DynamicParticle input
// 20100924  M. Kelsey -- Add constructor to copy G4Fragment input, and output
//      functions to create G4Fragment.
// 20110214  M. Kelsey -- Replace integer "model" with enum
// 20110225  M. Kelsey -- Add equality operator (NOT sorting!)
// 20110721  M. Kelsey -- Follow base-class ctor change to pass model directly
// 20110722  M. Kelsey -- BUG FIX:  Deleted excitation energy in one ctor
// 20110829  M. Kelsey -- Add constructor to copy G4V3DNucleus input
// 20110919  M. Kelsey -- Add clear() to restore completely empty state
// 20110922  M. Kelsey -- Add stream argument to printParticle() => print()
