* Begin support for multi-shape based detector (Gaspard) in NPAnalysis

   + TGaspardTrackerDummyShape.{h,cxx} and TGaspardTrackerTrapezoid.{h,cxx} added
      These classes will deal with reading the configuration, calculating the 
      geometry and building physical events.

   + TGaspardTrackerPhysicsNew.{h,cxx}
      This class holds the TGaspardTrackerData class and knows all the detectors
      to analyze through a map relating the detector number and the corresponding
      TGaspardTrackerModule object.

* Status:
   Configuration files with heterogeneous shapes are read and the map
   is filled correctly
