* Fixing minor bug in NPBeam and NPReaction

* 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

 - 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

*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.

 - 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

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

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

 - 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)

   + 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

  directory in NPLib

   + changes in all *.reaction event generator files were performed
   + update ReleaseNotes.txt file

* NPLib/Makefile
   + when make distclean, now remove NPToolLogon_C* files in scrips directory

* Modifing code of the Reaction and Detector Manager so you can also put absolute or relative path to the different file
 - Still support the use of environment path
 - Transparent for user, the two way are equivalent

	- Wrong mass was substract in ReconstructRelativistic
	- Replace some french variable name by english name

	- Now deal with case where the excitation energy lead below threshold
	- Breit-Wigner is nicely obtained from analysis
