   - mainly adds support for solid D2 cryogenic target

   - Effect of beam tracker is now taken into account

* Add new cross-section files

   - case for TInitialConditions, TInteractionCoordinates, 
     TGaspardTrackerData and TPlasticData
   - one method was added:    void Clear(const Option_t*) {};
   - one method was modified: void Dump() const;

   - Take into account energy loss in the target for reconstruction
     of the excitation energy
   - change makefile to recompile when header files are changed

* Clean some part of the code to remove warnings at compilation time

   - This is useful for elastic scattering studies

* Add CH2 material for target definition

* Change ushort for unsigned short in *.cc files

* Rename Gaspard geometry input files

* Add one differential cross section file

* New version of Gaspard analysis code

* Fill all fields of the TInitialCondition class for an isotropic event
  generator

   - Add TGaspardTrackerPhysics.{h,cxx} and GaspardTracker.{h,cxx} in NPLib
   - Correct a bug concerning the name of the InitializeScorers() method
