* REmove unjustified comment in configure script

   in order to compile only the part of DetectorManager
   which corresponds to the detector given as arguments
   of the configure script

   Now, one should first execute the configure
   script and then run make

 * There is the possibility to pass as arguments
   of the configure script detector names, e.g:
   ./configure must2 cats
   
 * Moreover, there is the possibility to compile
   specific detectors, e.g: make must2

   compatibility with Ganil2Root package

 * Add Chateau de Cristal files from Iolanda Matea
   experiment

   was not used]

   version (Pierre) supporting Confiuration File...

 * Getters in TCATSData.h now return a const result

 * Applythreshold() and GetPedestal() methods have
   been added in CalibrationManager. This is needed
   by the new TCATSPhysics version.

   (Speg + EXL + MUST2)

   accordingly. Needed in Speg analysis

 * Remove compilation warning in TSpegPhysics.cxx

 * Add GetCorrection() method in CalibrationManager
   Needed in Speg analysis

 * Update DetectorManager to take into account
   Speg, EXL

   variables initialised but not used

 * Add Speg and EXL to NPAnalysis

 * Add EXL detector in NPLib
 * Change Must2 Makefile and remove TMust2Spectra build
   since it was causing some unreliable behaviour

* adding #include<stdlib.h> to some file to fix compatibility with recent compilator (not recognizing the exit(int) method)

 - Note: the LED time is always null for the Tig64 card

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