+ For the class documentation see the corresponding header file.
+
+ Important revisions after version 2.0.0 :
+ @ Nov 30, 2007 - SD
+   Changed the hadron tracking algorithm to take into account the radial
+   nuclear density dependence. Using the somewhat empirical approach of
+   increasing the nuclear radius by a const (tunable) number times the tracked
+   particle's de Broglie wavelength as this helps getting the hadron+nucleus
+   cross sections right.
+ @ Mar 08, 2008 - CA
+   Fixed code retrieving the remnant nucleus which stopped working as soon as
+   simulation of nuclear de-excitation started pushing photons in the target
+   nucleus daughter list.
+ @ Jun 20, 2008 - CA
+   Fix a mem leak: The (clone of the) GHepParticle being re-scattered was not
+   deleted after it was added at the GHEP event record.
+ @ Jul 15, 2010 - AM
+   Major overhaul of the function of each interaction type. Absorption fates
+   changed to allow more than 6 particles at a time (up to 85 now). PiPro fates
+   now allow the pion to rescatter inside the nucleus, will be changed at a
+   later date. HAIntranuke class is now defined as derived from virtual class.
+   Intranuke.
+ @ Oct 10, 2011 - SD
+   Changes to keep reweighting alive.  Add exception handling in ElasHA, InelasticHA,
+   and Inelastic.
+ @ Jan 24, 2012 - SD
+   Add option of doing K+.
+ @ Jan 9, 2015 - SD, NG, TG
+   Added 2014 version of INTRANUKE codes (new class) for independent development.
+ @ Aug 30, 2016 - SD
+   Fix memory leaks - Igor.

+
+ For the class documentation see the corresponding header file.
+
+ Important revisions after version 2.0.0 :
+ @ Nov 30, 2007 - SD
+   Changed the hadron tracking algorithm to take into account the radial
+   nuclear density dependence. Using the somewhat empirical approach of
+   increasing the nuclear radius by a const (tunable) number times the tracked 
+   particle's de Broglie wavelength as this helps getting the hadron+nucleus 
+   cross sections right.
+ @ Mar 08, 2008 - CA
+   Fixed code retrieving the remnant nucleus which stopped working as soon as
+   simulation of nuclear de-excitation started pushing photons in the target
+   nucleus daughter list.
+ @ Jun 20, 2008 - CA
+   Fix a mem leak: The (clone of the) GHepParticle being re-scattered was not 
+   deleted after it was added at the GHEP event record.
+ @ Jul 15, 2010 - AM
+   The hN mode is now implemented in Intranuke. Similar to hA mode, but particles
+   produced by reactions are stepped through the nucleus like probe particles.
+   Particles react with nucleons instead of the entire nucleus, and final states
+   are determined after reactions are finished, not before.
+ @ Dec 15, 2014 - SD, Nick Geary 
+   Update fates to include Compound Nucleus final state correctly.
+ @ Jan 9, 2015 - SD, NG, Tomek Golan
+   Added 2014 version of INTRANUKE codes (new class) for independent development.
+ @ Oct, 2015 - TG
+   Added 2015 version of INTRANUKE codes (new class) for independent development.  Include Oset model for medium corrections to piA for Tpi<350 MeV.
+ @ May, 2015 Flor Blaszczyk
+   K+ are now handled.
+ @ July, 2016 Nicholas Suarez, Josh Kleckner, SD
+   fix memory leak, fix fates, improve NNCorr binning
+ & Mar, 2025  Nicholas Suarez, SD
+   add compound nucleus option to populate KE<30 MeV

+
+ Important revisions after version 2.0.0 :
+ @ Dec 06, 2008 - CA
+   Tweak dtor so as not to clutter the output if GENIE exits in err so as to
+   spot the fatal mesg immediately.
+ @ Jul 15, 2010 - AM
+   MeanFreePath now distinguishes between protons and neutrons. To account for
+   this, additional splines were added for each nucleon. Absorption fates
+   condensed into a single fate, splines updated accordingly. Added gamma and kaon
+   splines.Outdated splines were removed. Function IntBounce implemented to calculate
+   a CM scattering angle for given probe, target, product, and fate. AngleAndProduct
+   similar to IntBounce, but also determines the target nucleon.
+ @ May 01, 2012 - CA
+   Pick data from $GENIE/data/evgen/intranuke/
+ @ Jan 9, 2015 - SD, Nick Geary, Tomek Golan
+   Added 2014 version of INTRANUKE codes for independent development.
+ @ Oct, 2015 - TG
+   Added 2015 version of INTRANUKE codes for independent development.
+   Include Oset data files.
+ @ Apr, 2016 - Flor Blasczyk
+   Added K+ cex data files

+\class    genie::INukeHadroData
+
+\brief    Singleton class to load & serve hadron x-section splines used by
+          GENIE's version of the INTRANUKE cascade MC.
+
+          See $GENIE/src/HadronTransport/Intranuke.h for more details on the
+          INTRANUKE cascade MC developed primarity by S.Dytman and H.Gallagher
+          continuing older work from R.Edgecock, G.F.Pearce, W.A.Mann,
+          R.Merenyi and others.
+
+          The hadron x-section data used to build the x-section splines stored
+          at this singleton are provided & maintained by Steve Dytman.
+          See the data files in $GENIE/data/hadron_xsec/ for more details on
+          Steve's data sources and applied corrections.
+          In a nutshell:
+          The h+N x-sections come mostly from the SAID (Arndt et al.) PWA fit
+          while the h+A x-sections come from a combination of Ashery, Carroll
+          data and extrapolations, and INC model results from Mashnik et al.
+          for h+Fe56.

+   Was first added in v2.5.1. Adapted from the T2K GENIE reweighting tool.
+ @ Mar 05, 2009 - CA
+   Modified ReconstructHadronFateHA() to work with hadron+A event files in
+   addition to neutrino event files.
+ @ Sep 10, 2009 - CA
+   Added MeanFreePath(), Dist2Exit(), Dist2ExitMFP()
+ @ Sep 30, 2009 - CA
+   Added StepParticle() from Intranuke.cxx
+ @ Oct 02, 2009 - CA
+   Added test MeanFreePath_Delta().
+ @ Jul 15, 2010 - AM
+   Added common utility functions used by both hA and hN mode. Updated
+   MeanFreePath to separate proton and neutron cross sections. Added general
+   utility functions.
+ @ Jan 9, 2015 - SD, NG, TG
+   Added 2014 version of INTRANUKE codes for v2.9.0.  Uses INukeHadroData2014,
+   but no changes to mean free path.

+         September 20, 2005
+
+ For the class documentation see the corresponding header file.
+
+ Important revisions after version 2.0.0 :
+ @ Nov 30, 2007 - SD
+   Changed the hadron tracking algorithm to take into account the radial
+   nuclear density dependence. Using the somewhat empirical approach of
+   increasing the nuclear radius by a const (tunable) number times the tracked
+   particle's de Broglie wavelength as this helps getting the hadron+nucleus
+   cross sections right.
+ @ Mar 08, 2008 - CA
+   Fixed code retrieving the remnant nucleus which stopped working as soon as
+   simulation of nuclear de-excitation started pushing photons in the target
+   nucleus daughter list.
+ @ Jun 20, 2008 - CA
+   Fix a mem leak: The (clone of the) GHepParticle being re-scattered was not
+   deleted after it was added at the GHEP event record.
+ @ Jan 28, 2009 - CA
+   The nuclear remnant is now marked as a kIStFinalStateNuclearRemnant, not
+   as a kIStStableFinalState.
+ @ Sep 15, 2009 - CA
+   IsFake() and IsNucleus() are no longer available in GHepParticle.
+   Use pdg::IsPseudoParticle() and pdg::IsIon().
+ @ Sep 15, 2009 - CA
+   Store the rescattering code (hadron fate) in the GHEP record so as to
+   facilitate event reweighting.
+ @ Jul 15, 2010 - AM
+   Split Intranuke class into two separate classes, one for each interaction mode.
+   Intranuke.cxx now only contains methods common to both classes and associated
+   with the stepping of the hadrons through the nucleus and with configuration.
+ @ Nov 20, 2011 - CA
+   Tweaked the way TransportHadrons() looks-up the nuclear environment so that
+   it works for the nucleon decay mode as well.
+ @ Dec 08, 2011 - CA
+   Some minor structural changes. The new GEvGenMode_t is determined at the
+   start of the event processing and is used throughout. fInTestMode flag and
+   special INTRANUKE configs not needed. ProcessEventRecord() was added by
+   factoring out code from HNIntranuke and HAIntranuke. Some comments added.
+ @ Dec 23, 2014 - TG, SD
+   New 2014 class for latest Intranuke model
+ @ Apr 26, 2025 - SD
+   Change year 2015 to 2025

+\ref      R.Merenyi et al., Phys.Rev.D45 (1992)
+          R.D.Ransome, Nucl.Phys.B 139 (2005)
+
+          Current INTRANUKE development is led by S.Dytman and H.Gallagher.

+
+ For the class documentation see the corresponding header file.
+
+ Important revisions after version 2.0.0 :
+ @ Nov 30, 2007 - SD
+   Changed the hadron tracking algorithm to take into account the radial
+   nuclear density dependence. Using the somewhat empirical approach of
+   increasing the nuclear radius by a const (tunable) number times the tracked
+   particle's de Broglie wavelength as this helps getting the hadron+nucleus
+   cross sections right.
+ @ Mar 08, 2008 - CA
+   Fixed code retrieving the remnant nucleus which stopped working as soon as
+   simulation of nuclear de-excitation started pushing photons in the target
+   nucleus daughter list.
+ @ Jun 20, 2008 - CA
+   Fix a mem leak: The (clone of the) GHepParticle being re-scattered was not
+   deleted after it was added at the GHEP event record.
+ @ Jul 15, 2010 - AM
+   Major overhaul of the function of each interaction type. Absorption fates
+   changed to allow more than 6 particles at a time (up to 85 now). PiPro fates
+   now allow the pion to rescatter inside the nucleus, will be changed at a
+   later date. HAIntranuke class is now defined as derived from virtual class.
+   Intranuke.
+ @ Oct 10, 2011 - SD
+   Changes to keep reweighting alive.  Add exception handling in ElasHA, InelasticHA,
+   and Inelastic.
+ @ Jan 24, 2012 - SD
+   Add option of doing K+.
+ @ Jan 9, 2015 - SD, NG, TG
+   Added 2014 version of INTRANUKE codes (new class) for independent development.
+ @ Aug 30, 2016 - SD
+   Fix memory leaks - Igor.

+\ref      R.Merenyi et al., Phys.Rev.D45 (1992)
+          R.D.Ransome, Nucl.Phys.B 139 (2005)
+
+          Current INTRANUKE development is led by S.Dytman and H.Gallagher.
+          The original INTRANUKE cascade MC was developed (in fortran) for the
+          NeuGEN MC by R.Edgecock, G.F.Pearce, W.A.Mann, R.Merenyi and others.

+
+ For the class documentation see the corresponding header file.
+
+ Important revisions after version 2.0.0 :
+ @ Nov 30, 2007 - SD
+   Changed the hadron tracking algorithm to take into account the radial
+   nuclear density dependence. Using the somewhat empirical approach of
+   increasing the nuclear radius by a const (tunable) number times the tracked 
+   particle's de Broglie wavelength as this helps getting the hadron+nucleus 
+   cross sections right.
+ @ Mar 08, 2008 - CA
+   Fixed code retrieving the remnant nucleus which stopped working as soon as
+   simulation of nuclear de-excitation started pushing photons in the target
+   nucleus daughter list.
+ @ Jun 20, 2008 - CA
+   Fix a mem leak: The (clone of the) GHepParticle being re-scattered was not 
+   deleted after it was added at the GHEP event record.
+ @ Jul 15, 2010 - AM
+   The hN mode is now implemented in Intranuke. Similar to hA mode, but particles
+   produced by reactions are stepped through the nucleus like probe particles.
+   Particles react with nucleons instead of the entire nucleus, and final states
+   are determined after reactions are finished, not before.
+ @ Dec 15, 2014 - SD, Nick Geary 
+   Update fates to include Compound Nucleus final state correctly.
+ @ Jan 9, 2015 - SD, NG, Tomek Golan
+   Added 2014 version of INTRANUKE codes (new class) for independent development.
+ @ Oct, 2015 - TG
+   Added 2015 version of INTRANUKE codes (new class) for independent development.  Include Oset model for medium corrections to piA for Tpi<350 MeV.
+ @ May, 2015 Flor Blaszczyk
+   K+ are now handled.
+ @ July, 2016 Nicholas Suarez, Josh Kleckner, SD
+   fix memory leak, fix fates, improve NNCorr binning
+ & Mar, 2025  Nicholas Suarez, SD
+   add compound nucleus option to populate KE<30 MeV

+\brief    The INTRANUKE intranuclear hadron transport MC.
+          Is a concrete implementation of the EventRecordVisitorI interface.

+\ref      R.Merenyi et al., Phys.Rev.D45 (1992)
+          R.D.Ransome, Nucl.Phys.B 139 (2005)
+
+          Current INTRANUKE development is led by S.Dytman and H.Gallagher.
+          The original INTRANUKE cascade MC was developed (in fortran) for the
+          NeuGEN MC by R.Edgecock, G.F.Pearce, W.A.Mann, R.Merenyi and others.

+ For the class documentation see the corresponding header file.
+
+ Important revisions after version 2.0.0 :
+ @ Dec 06, 2008 - CA
+   Tweak dtor so as not to clutter the output if GENIE exits in err so as to
+   spot the fatal mesg immediately.
+ @ Jul 15, 2010 - AM
+   MeanFreePath now distinguishes between protons and neutrons. To account for
+   this, additional splines were added for each nucleon. Absorption fates
+   condensed into a single fate, splines updated accordingly. Added gamma and kaon
+   splines.Outdated splines were removed. Function IntBounce implemented to calculate
+   a CM scattering angle for given probe, target, product, and fate. AngleAndProduct
+   similar to IntBounce, but also determines the target nucleon.
+ @ May 01, 2012 - CA
+   Pick data from $GENIE/data/evgen/intranuke/
+ @ Jan 9, 2015 - SD, Nick Geary, Tomek Golan
+   Added 2014 version of INTRANUKE codes for independent development.
+ @ Oct, 2015 - TG
+   Added 2015 version of INTRANUKE codes for independent development.
+   Include Oset data files.
+ @ Apr, 2016 - Flor Blasczyk
+   Added K+ cex data files

+\class    genie::INukeHadroData
+
+\brief    Singleton class to load & serve hadron x-section splines used by
+          GENIE's version of the INTRANUKE cascade MC.
+
+          See $GENIE/src/HadronTransport/Intranuke.h for more details on the
+          INTRANUKE cascade MC developed primarity by S.Dytman and H.Gallagher
+          continuing older work from R.Edgecock, G.F.Pearce, W.A.Mann,
+          R.Merenyi and others.
+
+          The hadron x-section data used to build the x-section splines stored
+          at this singleton are provided & maintained by Steve Dytman.
+          See the data files in $GENIE/data/hadron_xsec/ for more details on
+          Steve's data sources and applied corrections.
+          In a nutshell:
+          The h+N x-sections come mostly from the SAID (Arndt et al.) PWA fit
+          while the h+A x-sections come from a combination of Ashery, Carroll
+          data and extrapolations, and INC model results from Mashnik et al.
+          for h+Fe56.

+
+ For the class documentation see the corresponding header file.
+
+ Important revisions after version 2.0.0 :
+ @ Nov 30, 2007 - SD
+   Changed the hadron tracking algorithm to take into account the radial
+   nuclear density dependence. Using the somewhat empirical approach of
+   increasing the nuclear radius by a const (tunable) number times the tracked
+   particle's de Broglie wavelength as this helps getting the hadron+nucleus
+   cross sections right.
+ @ Mar 08, 2008 - CA
+   Fixed code retrieving the remnant nucleus which stopped working as soon as
+   simulation of nuclear de-excitation started pushing photons in the target
+   nucleus daughter list.
+ @ Jun 20, 2008 - CA
+   Fix a mem leak: The (clone of the) GHepParticle being re-scattered was not
+   deleted after it was added at the GHEP event record.
+ @ Jan 28, 2009 - CA
+   The nuclear remnant is now marked as a kIStFinalStateNuclearRemnant, not
+   as a kIStStableFinalState.
+ @ Sep 15, 2009 - CA
+   IsFake() and IsNucleus() are no longer available in GHepParticle.
+   Use pdg::IsPseudoParticle() and pdg::IsIon().
+ @ Sep 15, 2009 - CA
+   Store the rescattering code (hadron fate) in the GHEP record so as to
+   facilitate event reweighting.
+ @ Jul 15, 2010 - AM
+   Split Intranuke class into two separate classes, one for each interaction mode.
+   Intranuke.cxx now only contains methods common to both classes and associated
+   with the stepping of the hadrons through the nucleus and with configuration.
+ @ Nov 20, 2011 - CA
+   Tweaked the way TransportHadrons() looks-up the nuclear environment so that
+   it works for the nucleon decay mode as well.
+ @ Dec 08, 2011 - CA
+   Some minor structural changes. The new GEvGenMode_t is determined at the
+   start of the event processing and is used throughout. fInTestMode flag and
+   special INTRANUKE configs not needed. ProcessEventRecord() was added by
+   factoring out code from HNIntranuke and HAIntranuke. Some comments added.
+ @ Dec 23, 2014 - TG, SD
+   New 2014 class for latest Intranuke model
+ @ Apr 26, 2025 - SD
+   Change year 2015 to 2025

+          Current INTRANUKE development is led by S.Dytman and H.Gallagher.
+          The original INTRANUKE cascade MC was developed (in fortran) for the
