Al and Kapton material added to Plastic

 - Still not functionnal
 - Can read input file and instantiate properly
 - Does not do any physics yet

+ Small bug in histogram size for TTiaraHyballSpectra

 - Some old machine requiered the -e flag in front of echo to interpret correctly the \t command as a tab
- some new machine ignore -e and the make fail later
- The solution to both is to suppress the -e flag (done before) and replace \t by the ascii code \011

  header and src files of each defined detector are now
  symlinked in the include and src directory instead of
  being hard copied

* Remove compilation warnings in Tigree.cc

  this branch is dedicated to the conditional compilation of NPS

- Sin theta was not applied to the cross section

 - In the case of multiinteraction in the same volume, the scorer was keeping only the last energy deposit, instead of summing them
 - The threshold has been move in the Read sensitive and is no longer in the scorer, as the energy deposit can be down in multiple step each of them below threshold and be ignored if the threshold is applyed individually.

* Fixing GeometricalEfficiency.C macro to fit new TInitialCondition
* Adding support for TInitialCondition in Sharc

 - The target was not created and thus the Material not register in the dE/dx table. So NPS crash when trying to write the table. The table is no longer written if the size of the target is 0

* Fixing issue when EventGeneratorIsotropic is used for gamma emission

 - Placement of Box detector Ok for Pad and Single layer case
 - Restauring original colour of the PCB

 - step 2: adding back the file

- Setp 1: remove the problematic file

 - The line starting with % was not ignore during the reading phase

   This is the version used during the 
   e611 experiment

 - Add associate class in NPL
 - Add Function in NPL

Some code clean up has been done as well (cosmetic change for the most)

   (Speg + EXL + MUST2)

- QQQ working
- Adding PAD in progress

- Box Detector Ok
- QQQ starting

* Progress on the Sharc detector
* Correcting bug on the particle stack: Initial condition was not cleared at end of event, generating massive root file

 - 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

* Changing old naming convention ThinSi to SSSD

   + 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
