virtual void SetFirstParton(G4int PDGcode)
virtual void SetSecondParton(G4int PDGcode)
to set quark (anti-quark) determination at the annihilation.

----------------------------------------------------
3 August 2009, V. Uzhinsky (hadr-prtn-V09-02-02)
FTF model was complited by the reggeon cascade model.
-----------------------------------------------------------
17 July 2009 V. Uzhinsky (hadr-prtn-V09-02-01)
Improvement of FTF model:
A Status of nuclear nucleon involved in an interaction is introdused.
Status: 0 - spectator, 1 - involved nucleon, 2 - absorbed nucleon
(G4VSplitableHadron)
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 in FTF.
-------------------------------------------------
10 July 2009 V. Uzhinsky (hadr-prtn-V09-02-00)
Introduction the right tag number.
-------------------------------------------------
9 July 2009 V. Uzhinsky (hadr-prtn-V09-01-03)
Charge-exchange was implemented for pn->np in elastic and inelastic
interactions simulated by FTF. Pion absorption by a nucleon was
implemented also. tag - hadr-string-diff-V09-02-02
Bug was fixed in G4VLongitudinalStringDecay.cc at calculation of
formation/creation time, c_light was inserted. Due to this string
tension parameter was set to the usual value (1 GeV/fm) in
G4LundStringFragmentation.cc. tag - had-hadronization-V09-02-02
New field was added in G4VSplitableHadron class (G4 bool Activation)
and corresponding methods to operatite with it. It was needed for an
absorption of meson in nuclear collision generated by FTF.

-----------------------------------------------
23 June 2008 V. Uzhinsky (hadr-prtn-V09-01-02)
G4QGSMFragmentation.cc and G4LundStringFragmentation.cc were
decoupled at calculation of formation time due to adding methods
and member in G4VLongitudinalStringDecay class for manipulation
with string tension.
Memory leak was erased in G4QGSMFragmentation.cc and
G4VLongitudinalStringDecay.cc thank to Gunter.
18 June 2008 V. Uzhinsky (hadr-prtn-V09-01-01)

operation of FTF.

- Move G4SingleDiffractiveExcitation from management to qgsm ( not used
elsewhere)

23 Nov 2005 Dennis Wright (hadr-prtn-V07-01-00)
-----------------------------------------------
- G. Folger fixed bug in hadronization/G4ExcitedStringDecay.cc

31 March 2008 V. Uzhinsky (hadr-string-diff-V09-01-00)
--------------------------------------------------------
- Elastic hadron intra-nuclear nucleon scattering was inserted in
FTF model. This allows to simulate quasi-elastic and multi-particles
production together.
- Small re-orangement of FTF model was done. G4FTFCrossSection modules
were re-named into G4FTFParameters and moved to /diffraction
