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.

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

   + if NPLib was not compiled, error concerning libVDetector.so loading
     was obtained when starting ROOT (now fixed).

 - Put all threshold as an option through configMUST2.dat
 - Add better support for matching between strip and cristal/pad
 - Add option to set the cristal / pad size
 - Add option to ignore in data event between cristal/pad
 - Renaming Namespace to avoid conflict
 - Renaming variable to be consistent

* Change in TSSSDPhysics
 -Change the routine for configSSSD.dat, consistent with MUST2

* Change filllibdir.h
 - Remove NPToolLogon_C.so from lib dir to avoid error message on linux

   + return to initial directory now uses the gSystem->cd() method
   + change InitNPTool fucntion name for NPToolLogon (it was now compiling
     on Mac os X)

* Update some doc files to explain logic of NPToolLogon.C

* Fix bug in ControlSimu.C

 - no the current directory stay the main directory
 - quiet mode can be call
 - a function is compiled in order to support cout on all platforme

  when a ROOT session starts.
     + header directory (NPLib/include) is declared
     + libraries in NPLib/lib are loaded

* new version of the rootlogon.C file calling the NPToolLogon.C script.

                           u = (128,1) - (1,128)
       w = u x v in direction of third stage

* Cartesian and spherical positioning of GaspardTrackerTrapezoid is consistent

* gaspHyde.detector has been modified to take these changes into account

* Stripping scheme in NPS and NPA still to be done

   + makefile.sh script added
   + this script loop on all sub-directories containing a Makefile and 
     run it.

   + scripts are used to move header files, libraries to the include and
     lib directories
   + scripts are located in NPLib/scripts
   + liblist is know created on the fly and is removed from the NPTool 
     package

* Update NPL Makefile to include Paris and Shield detectors
