- optional token, keeping retrocompatibility
 - allow to use "beam" at rest as source for gamma cascade

 - Delete the actual geometry
 - Clear the Detector Manager
 - Reload Geometry file

For this to work a couple of thing has been done:
 - InitializeRootInput now need an extra SetBranchAddress to tell the
   tree that the previous address is no longer in use
 - Scorer can not be cleared, so need to be retrieved in case of a
   reloading. If they do not exist they are created
 - This is done using the new CheckScorer static method from VDetector

* outputted incorrectly

* Fixing minor bug in NPBeam and NPReaction

* Updating copyright
* adding AnnularS1Physics class

* The code compile and run but still need confirmation that it work as
* expected
* Modification does not affect the usual single differential way of
* working

* double deletion of histogramms by Root and the cause a seg fault when
* leaving cint

 - in rare case wrong time was assigned to the wrong energy for Silicon
* Cosmetic change un TMust2Physics for better code readbility

 - Similar mecanism to the CS system
 - Allow user to provide a random Ex distribution in txt or root file
   format
* Changing Display of Gaspard, Paris and Must2 detector for the GMAP_LOI preparation

Al and Kapton material added to Plastic

*Adding some getter in NPreaction

 - Some old machine requiered the -e flag in front of echo to interpret correctly the \t command as a tab
- some new machine ignore -e and the make fail later
- The solution to both is to suppress the -e flag (done before) and replace \t by the ascii code \011

- Sin theta was not applied to the cross section

 - In the case of multiinteraction in the same volume, the scorer was keeping only the last energy deposit, instead of summing them
 - The threshold has been move in the Read sensitive and is no longer in the scorer, as the energy deposit can be down in multiple step each of them below threshold and be ignored if the threshold is applyed individually.

 - The code was returning the atomic mass instead of the nuclear one

 - NPS was giving conflict between NP system of Unit and CLHEP one, this is was fixed by a nested ifdef on HEP_SYSTEM_OF_UNIT

* Fixing issue with S1:
 - in Detector Manager a tipo was desabling the condition compilation of S1

* Fixing issue in Isotropic:
 - conflict when the particle was light nuclei given by its name (eg proton instead of 1H)
 - Problem is fixed and user can use gamma, proton, deuton, triton and alpha spelling

   + this allows to remove CLHEP dependency in NPLib
   + this allows to remove Constant.h file

 - NPReaction: The Cint Dict generation need the destructor to be of type virtual to be overloaded safely by the dictionnary
 - TSharcPhysics: Some variable embeded in if statement migth be used uninitialised from a compilation point of view.

 - Fixing bug in particle and gamma dicay causing seg fault when leaving the program
 - fixing bug in NP function caussing 2Dgaussian to be stuck for sigmaX=sigmaY=0 case

* clean up the Physics list file (remove trailling comment and reindent)
* fix cout issue in event action

 - putting the update date 2009-2013
 - Adding some missing liscence header
 - moving some #ifndef to avoid copy of comment
 - fixing minor compilation bug in TSpegPhysics

 - Try as an absolute or relative path
 - if fail try in the standard location
 - if fail exit with error code 1

 - Renaming of private member of Initial Condition
 - Beam energy was not set in Read Configuration

   default initialization of min, max, xmin, xmax to 0

 * Update Speg analysis so the event generator is 
   taken directly from the command line

 - fixing couple of bug
 - remove some warning
 - enhance performance
