  from sources.cmake

22 November 2013 W. Pokorski (hadr-lepnuc-V09-06-04)
---------------------------------------------

in order to have reproducibility. To be properly fixed later.

11 September 2013 W. Pokorski (hadr-lepnuc-V09-06-03)
---------------------------------------------

---------------------------------------------

04 September 2013 W. Pokorski (hadr-lepnuc-V09-06-01)

4 October 2012  G. Cosmo  (hadr-lepnuc-V09-05-01)
-------------------------------------------------

24 September 2012  D.H. Wright  (hadr-lepnuc-V09-05-00)
-------------------------------------------------------
- create new lepto-nuclear directory containing only the
  G4ElectroVDNuclearModel and G4MuonVDNuclearModel classes.  Begin new tag
  name sequence as well.

  pion momentum at low gamma energies

8 June 2012  D.H. Wright     (hadr-munuclear-V09-05-06)

- G4ElectroVDNuclearModel.cc : replace variable "m2" which shadows
  a CLHEP variable

-------------------------------------------------------
- fix bug in sources.cmake

18 May 2012  D.H. Wright     (hadr-munuclear-V09-05-03)
-------------------------------------------------------
- added new model G4ElectroVDNuclearModel
- remove classes G4LeptonHadronProcess and G4LeptonHadronInteractionModel
- changed name of G4VDMuonNuclearModel to G4MuonVDNuclearModel to 
  avoid any confusion with virtual class names

 7 May 2012  D.H. Wright     (hadr-munuclear-V09-05-02)
------------------------------------------------------
- G4VDMuonNuclearModel: for gammas below 10 GeV use Bertini cascade to
  interact gammas directly with nucleus.  Above 10 GeV, treat gamma as
  pi0 and use FTFP model.

---------------------------------------------------
- G4MuNuclearInteraction added SubType and registration in the 
                         G4HadronicProcessStore; added PreparePhysicsTable
                         method and cleanup for readability
