   FTF parameters have been tunned on hN-interactions.
   Binary reactions were introduced and checked.

  Kaon A interactions are improved in FTFModel.
----------------------------------------------------------
6 August 2009, V. Uzhinsky (hadr-string-diff-V09-02-10)
  A warning message at FTFmodel compilation connected with Xminus
  initialisation was erased.
----------------------------------------------------------
5 August 2009, V.Uzhinsky (hadr-string-diff-V09-02-09)

-----------------------------------------------------------
3 August 2009, V. Uzhinsky (hadr-string-diff-V09-02-07)
   FTF model with the reggeon cascading was complited by
   formation time for a following coupling with the binary model.
-----------------------------------------------------------
31 July 2009, V. Uzhinsky (hadr-string-diff-V09-02-06)
   Inconsistency in G4FTFModel was erased thank to Gunter.

----------------------------------------------------------
31 July 2009, V. Uzhinsky (hadr-string-diff-V09-02-05)
   The reggeon theory inspired model of duclear desctruction is
   implemented for a simulation of low particle cascading.
   The code can operate with Precompound model only.
-------------------------------------------------------------------

17 July V. Uzhinsky        (hadr-string-diff-V09-02-04)
   A Status of nuclear nucleon involved in an interaction is introdused.
   Status: 0 - spectator, 1 - primary involved nucleon, 2 - a nucleon
   involved in the reggeon cascading, 3 - absorbed nucleon.

   A connection between a participant nucleon and a nuclear nucleon was
   introsuced in G4InteractionContent.

   All of these allow to improve FTF model for pion obsorption on nuclei.
   These required a lot of changes.
---------------------------------------------------------

10 July V. Uzhinsky        (hadr-string-diff-V09-02-03)
Bug was fixed in G4FTFModel.cc thank to A. Ribon
---------------------------------------------------------
9 July 2009 V. Uzhinsky    (hadr-string-diff-V09-02-02)
- Charge-exchange was implemented for pn->np 
  elastic and inelastic interactions.
- Pion absorption by a nucleon was implemented. 
  See comments marked by Uzhi 07.07.09
---------------------------------------------------------
19 December 08 V. Uzhinsky (hadr-string-diff-V09-02-01)
---------------------------------------------------------
 Version of FTF suted for low energies (2-10 GeV/c)

9 December 08, V. Uzhinsky (hadr-string-diff-V09-01-04)
- Improvement of delete operators in FTF

5 December 08, V. Uzhinsky (hadr-string-diff-V09-01-03)
- Some objects did not erase in FTFModel desructor. These lead to memory 
  leak.


2 June 08, G.Folger 		(hadr-string-diff-V09-01-02)
-  on branch geant4-09-01-patches_branch, fix compilation warning for unused 
     variables in G4FTFModel.cc
     


??????????????????????????????      (hadr-string-diff-V09-01-01)

31 March 2008 V. Uzhinsky           Tag : hadr-string-diff-V09-01-00
- G4FTFParameters.cc and G4FTFParameters.hh were copied from G4FTFCrossSection
  corresponding files.
- New files - G4ElasticHNScattering have been added. They implement elastic 
  scattering of hadron in intra-nuclear collisions in FTF model.
- The corresponding changes have been done in G4FTFModel.cc and 
  G4FTFParticipants.cc

  
24 Apr 2007 Gunter Folger  (hadr-string-diff-V08-02-00)
-  merge in change done by ftf development.
- Created History file.
