- Sin theta was not applied to the cross section

* Fixing GeometricalEfficiency.C macro to fit new TInitialCondition
* Adding support for TInitialCondition in Sharc

   + return to initial directory now uses the gSystem->cd() method
   + change InitNPTool fucntion name for NPToolLogon (it was now compiling
     on Mac os X)

* Update some doc files to explain logic of NPToolLogon.C

* Fix bug in ControlSimu.C

   + bug was in the correspondance between strip number and coordinates
   + excitation energy is now well reconstructed

* Add Destroy method in the singleton class NPOptionManager
   + it is used in the Gaspard analysis code

* Change default ROOT file name in general analysis macros
   + mySimul.root is now myResult.root

* Add DumpStrippingScheme method in GaspardTracker
   + it allows to dump the correspondance between strips and coordinates
     for any detector part of Gaspard
   + for the moment indexes are hardcoded for annular detector (should be
     improved)

   - mainly adds support for solid D2 cryogenic target

* Fix bug when writing G4 energy loss tables in EventGeneratorTransfert

* Update Gaspard Analysis and controls macro

* New directory: Misc
    - put NPEnvironment.* files and rootlogon.C file here

* Add DisplayInputCrossSection.C file in Gaspard Analysis

  + the index of all maps now includes the number of the detector

No commit message

   - Limitation: only works for beams parallels to the optical axis
     (no beam divergence)
   - Only implemented for the moment in EventGeneratorTransfer.cc

* Changes in the INSTALL files to insist on having a working GSL install
  and a ROOT MathMore module

* New version of Gaspard analysis code
