tracks using Stepping Action. 2) Add to the p2p reaction the possibility
for the heavy nucleus to decay using the ABLA deexcitation code included
  in G4.

        - name convention in geant4 is different for g.s and excited
        state

* updating copyright
* updating a matta email

* energy loss table name

  last line was read twice and then giving wrong number of bins

+ more efficient code for skipping comment lines and for the
  determination of min and max

 - in rare case wrong time was assigned to the wrong energy for Silicon
* Cosmetic change un TMust2Physics for better code readbility

 - Fixing bug in particle and gamma dicay causing seg fault when leaving the program
 - fixing bug in NP function caussing 2Dgaussian to be stuck for sigmaX=sigmaY=0 case

   default initialization of min, max, xmin, xmax to 0

 * Update Speg analysis so the event generator is 
   taken directly from the command line

 - 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)
