- For now only a copy of CalorimeterScorers
  - Adapted CMakeLists.txt

Several updates related to STRASSE and addition of a GAGG detector as well as several small improvement

Updating Scone, ChiNu and PISTA detectors

Nbr
        - The issue was in the Calorimeter scorer
        - The size of the level vector was access via a static

	- The Hit Level vector was not cleared at the begining of event

        - the t_level internal variable was not cleared at each event

        - Less read out code
        - Better memory management
        - Faster simulation

        - allow arbitrary geometry
        - can be used to simulate interstrip and dead layer
        - Use a base class NPImage to manage the image information
        - switch must2 to new scorers
        - fix must2 limitation to event with less particle than
          telescope (issue #17)

        - Now use separate folder for scorer, event generator and
          physics

* old one
* Run replace.sh to replace old matta@ipno.in2p3.fr address

* updating copyright
* updating a matta email

Update of Hira.cc for the CsI crystal geometry: G4Trd->G4Trap and modification of NestingLevel for the copy number of CsI Crystal

  - Now follow the new logique
  - Less file
  - Updated geometry

* Advancing Tiara Barrel Simulation, now working (still to be tested
extensively)
