* 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.

   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

  experiments.

  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.

   + itoa() function now uses sprintf instead of ostringstream

   + This class holds the spetra which are needed for the online analysis
     of Must2 experiments
   + However, this class only depends on ROOT and can be used in any context.
   + This is a first uncomplete version which has not been tested yet.

   + Add new method SetRawDataPointer(TxxxData*) which gives by hand the 
     TxxxData object to the corresponding TxxxPhysics object

* Change InitializeRootInput() method for InitializeRootInputRaw() for
  Gaspard, Hyde and Paris project.
