// Defines enums to map G4InuclElementaryParticle type codes to human
// readable names.  Meant to replace similar local enums scattered through
// the code.
//
// 20101029  M. Kelsey -- Move antinucleons to 50-series, add deuteron
// 20111007  M. Kelsey -- Change photon code to 9, for use in initial states
// 20130508  D. Wright -- Add leptons and electroweak bosons
// 20130627  M. Kelsey -- Add functions to convert enum to strings for printing
// 20130702  M. Kelsey -- Add type classifiers ported from G4InuclElemPart
