* Fixing issue with Materal Manager: Mylar and Kapon were improperly
* define

+ Change permissions for MUGAST analysis files
+ Update ControlSimu.C macro

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

* adding Dictionnary for VDetector class to avoid error message in root

* outputted incorrectly

 - 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

 - 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

  header and src files of each defined detector are now
  symlinked in the include and src directory instead of
  being hard copied

* Remove compilation warnings in Tigree.cc

   + 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

 - 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 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

 - 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

 - Basic Test indicate that the logic work well
 - Still requiered a real analysis to be all check

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

 - Can emmit gamma or nuclei
 - use the particle stack

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

 - Only one read configuration file method
 - lighter code
 - possibility to use TH1F for cross section shoot

 - Add associate class in NPL
 - Add Function in NPL

Some code clean up has been done as well (cosmetic change for the most)

   (Speg + EXL + MUST2)

- Box Detector Ok
- QQQ starting

* Progress on the Sharc detector
* Correcting bug on the particle stack: Initial condition was not cleared at end of event, generating massive root file
