- 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

 - 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)

  environment variables.

* The $NPTOOL env. variable is now the only one to be defined for
  running the project.

* Add comments in the $NPTOOL/NPLib/liblist file to specify that
  this file is created automatically.

   + Add HalfOpenAngleMin and HalfOpenAngleMax token in Transfert* files
     to take into account correctly the case where the user want to 
     specify angular range
   + This also takes into account cases where the cross-section file has
     a limited angular range

  in the reaction.

 - Suppress all Tab
 - Arrange indentation
