* Support for multi-shape based detector (Gaspard) in NPTool

   + A lot of work has been done

   + TGaspardTrackerPhysicsNew class
     This class now *only* hold the physical information as calculated
     from NPAnalysis.

   + Status:
     running NPAnalysis gives the same results with the new structure
     than before in case of the gaspardTestSpheric detector (only one
     shape)

   + Everything is prepared for multi-shape but whould be tested
