  detector

+ ongoing work for adapting GaspardTrackerAnnular to the new
  scorer scheme

 - Delete the actual geometry
 - Clear the Detector Manager
 - Reload Geometry file

For this to work a couple of thing has been done:
 - InitializeRootInput now need an extra SetBranchAddress to tell the
   tree that the previous address is no longer in use
 - Scorer can not be cleared, so need to be retrieved in case of a
   reloading. If they do not exist they are created
 - This is done using the new CheckScorer static method from VDetector

* editing the NPSimulation UI for nicer interface
 - adding menue and icon for common command
 - adding free icons for nice interface

* Adding creation of small sample cube by the material manager to ensure
* every declared material are used, so no crash when writting the DEDX
* tables

 - all material were always define but not use, causing crash in DEDX
   table output
- code clean up for Plastic.cc

* adding Dictionnary for VDetector class to avoid error message in root

* outputted incorrectly

* committed prototype

* Updating copyright
* adding AnnularS1Physics class

 - Similar mecanism to the CS system
 - Allow user to provide a random Ex distribution in txt or root file
   format
* Changing Display of Gaspard, Paris and Must2 detector for the GMAP_LOI preparation

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
