+ geant4 files are kept in the include and src directories
   + one directory is created for each detector. This directory
     contains the associated headers and sources files
   + a script directory is created with some scripts allowing the
     conditional compilation

 * Add #ifdef statements in DetectorConstruction.cc file
   + this applies to each detector header

 * Move G4MultiFunctionnalDetector.hh header from Sharc.cc to 
   Sharc.hh

  this branch is dedicated to the conditional compilation of NPS

- 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.

* Fixing GeometricalEfficiency.C macro to fit new TInitialCondition
* Adding support for TInitialCondition in Sharc

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

 - The DetectorThickness token has no effect

 - Beam was creating a never used Initial Condition
 - The hollow branch appear only on Linux(?) computer...

 - The target was not created and thus the Material not register in the dE/dx table. So NPS crash when trying to write the table. The table is no longer written if the size of the target is 0

* Fixing issue when EventGeneratorIsotropic is used for gamma emission

 - 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

 - Tree was not declared in non proof mode

 - The analysis project is in pMakePhysicalTree
 - The macro is launch putting the usual NPTool option in the macro string argument
 - Parrallel computation and merging of the output tree in memory (not suitable for very large run...)
 - Some change in the ROOTOuput to fit the requierement of pROOF, using the NPTOptionManager option --proof to activate them

 - The NPA project where not changed to include the new file and keep old ref to CLHEP path

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

 - Set and get are inline
 - Set and Get have const argument given by reference

- Sharc Tigress and Trifoil are now stand alone, no mixeup with the Unpacker (Triumf code) needs

 - 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.
