// Defines an interface to Bertini (BERT) cascade
// based on INUCL  intra-nuclear transport.models 
// with bullet hadron energy ~< 10 GeV
//
// 20100405  M. Kelsey -- Fix constness of op== and op!=
// 20100519  M. Kelsey -- Remove Collider data members
// 20100617  M. Kelsey -- Make G4InuclCollider a local data member
// 20100723  M. Kelsey -- Move G4CollisionOutput here for reuse
// 20100916  M. Kelsey -- Add functions to encapsulate ApplyYourself() actions,
//      make colliders pointers (don't expose dependencies)
// 20100922  M. Kelsey -- Add functions to select de-excitation method
// 20110224  M. Kelsey -- Add createTarget() for use with Propagate(); split
//      conservation law messages to separate function.  Move verbose
//      setting to .cc file, and apply to all member objects.
// 20110301  M. Kelsey -- Add copyPreviousCascade() for use with Propagate()  
//      along with new buffers and related particle-conversion  
//      functions.  Encapulate buffer deletion in clear()
// 20110303  M. Kelsey -- Change "bulletList" name to "inputFragments"
// 20110304  M. Kelsey -- Drop conversion of Propagate() arguments; pass
//      directly to collider for processing.  Rename makeReactionProduct
//      to makeDynamicParticle.
// 20110502  M. Kelsey -- Add filename string to capture random seeds.
// 20110720  M. Kelsey -- Discard elastic-cut array (no longer needed),
//      discard local "theFinalState" (avail in base class).
// 20110801  M. Kelsey -- Make bullet and target buffers local objects (with
//      hadron and nucleus versions) to reduce memory churn
// 20120522  M. Kelsey -- Implement base class IsApplicable, and add overloaded
//      version which takes G4ParticleDefintion, a la G4VProcess.
// 20120822  M. Kelsey -- Add function to dump user configuration settings.
//      Remove local verboseLevel; shadows base class data member.
// 20130501  M. Kelsey -- Add static initializer to created shared objects.
// 20130628  M. Kelsey -- Address Coverity warnings about copy operations.
// 20140116  M. Kelsey -- Move statics to const data members to avoid weird
//      interactions with MT.
