! angular ditribution from an TH1F histogram to simulate p, d, t...

* fixing warning in physics list
* adding MUGAST+AGATA detector file
* adding MUGAST chamber

        - OpticalPhoton are now correctly generated and tracked

* in the detector without leaving any energy

 - Some old machine requiered the -e flag in front of echo to interpret correctly the \t command as a tab
- some new machine ignore -e and the make fail later
- The solution to both is to suppress the -e flag (done before) and replace \t by the ascii code \011

   + Call to AddDetector() method was missing

* Finish NPAnalysis for W1 detector
   + Cases with multiplicity greater than one are treated
   + Excitation energy is reconstructed OK without strip
   + Excitation energy taking into account strips should be checked
     in more details.

* Cosmetic for screen printing in NPLib classes

   + NPSimulation is working
   + Scorers are working

* Add input files

   + 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)

   + NPS and NPA are consistent in case of Trapezoid shape placed in
     cartesian coordinates.
   + This should be checked when Trapezoid shape is placed in spherical
     coordinates.

* Removing old files in NPLib/Gaspard

   + Theta and Phi strips are added

* Cosmetic changes in AnnularS1.cc

	- Now can deal with squarred and cylindrical shape
	- Now can deal with spherical and cartesian coordinate

	- Now the weight of each event is stored instead of using a rejection methods when making the phase space decay

* Adding a pure phase space Event Generator
	- Using an input file, one can simulate any many body phase space (up to 18 body)
	- Same weight methods is used as in TransfertToResonance

	- Wrong detector name was given, problem fixed

* Setting a hi-cup on secondaries
	- There is no more secondaries generated (especially e- in the cryo target)

   - the output is now on a single line

* Add some documentation for Gaspard (not yet finished)
