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.

   + Clear for map scorers was misplaced at the end of all ReadSensitive()
     methods in GaspardTracker* shapes.
   + The same applied for the DetectorNumber_itr++ statement
   + The line Energy_itr = EnergyHitMap->GetMap()->begin(); was missing
     when looping on the energy map.

* Strip numbers are now integer instead of double

   + 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

     and 'ba48d78c46eba62f6e735937d048b2db4f5d6be3'

* renaming Must2Scorer to MUST2Scorer in NPS

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

     and 'b7a04db202b089e66ff768f951b47d4032bf35a6'

 - MakeFriendTrees("RunToRead1","RunToRead2")
 - can be called within CINT

 - Now Detector have two method to initialize the root input, one for the Raw data and one for physical data
 - An option ca be given in NPA to specified the input is of physical type

* Identify and correct some bug on the SSSD

     and '3ca0fc472267455880bd7ac2d83535dc85a83247'

   + limit on deposited energy for each step is now 0.1 keV instead of 100 keV
   + this produced double kinematical lines spaced by 100 keV

* Changing old naming convention ThinSi to SSSD

 - project contain macro for thickness correction for SSSD used with Must2

* Adding Calibration Macro for Must2 in the macro folder in NPA must2

 - Template can be used also to make physical tree, so it is renamed MakePhysicalTree

 - Limited Test only e530 data
 - Class may need future update to fit NPTool Standard

   + 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

   + G4MultipleScattering.h headers removed for 
     G4eMultipleScattering, G4hMultipleScattering, G4MuMultipleScattering

   -install_name $(CURDIR)/ had to be removed because NPSimulation was not
   executing anymore

* New Makefile and file arrangements for Gaspard in NPAnalysis
