- 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

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

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

* changing vis.mac file to use OGLI instead of OGLIQt interface

* The proton were registered as ion and did not interect any mor

* outputted incorrectly

* committed prototype

* Fixing minor bug in NPBeam and NPReaction

* Updating copyright
* adding AnnularS1Physics class

* Sharc scorer are now named SIlicon Scorer
* GeneralScorer moved to ObsoleteGeneralScorer
* The Obsolete Scorer are kept until all detector are move to the new
* syle of scorer

  - Wafer and PCB cutout
  - Active and Wafer geometry is accurate
  - PCB information need to be confirmed but are realistic

 - 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

  - Should be 1 was -1

+ TTiaraHyballSpectra now aware of TTiaraPhysics
