code and to keep track of all tags.

  from sources.cmake

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

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

  name sequence as well.

22 May 2012  D.H. Wright     (hadr-munuclear-V09-05-04)
-------------------------------------------------------
- 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
- sources.cmake: remove files and dependencies corresponding to above changes 

 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.

1 May 2012, D.Wright        ( ..trunk.. )
-------------------------------------------------------
- revert changes by Mikhail ( rev. r58262)
-    added to History 2-May 2012, G.Folger

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