- Adding test to travis CI

        - User need to provide a macro path with B flag
        - No Vis or GUI macro are executed in batch mode

        - Macro support any command except exit
        - exit cause the macro to stop, not Geant4
        - I don't have any fix for this yet ;)

        - gcc get confused by global variable and do not mangle the name
        correctly
        - fixed by removing the global varaible in question to
        NPOptionMnager

* Adding version number display

* use full for fast debugging and fast analysis

  - CMake compilation
  - PlugIn API for detector
  - Dynamic Loading of detector library at RunTime

+ Remove NPTagManager class

 - VDetector now have SPectra related classes
 - Detector Manager take care of calling the associate method
 - Still, the writing of the histogramm classes is to be done

 - The analysis project is in pMakePhysicalTree
 - The macro is launch putting the usual NPTool option in the macro string argument
 - Parrallel computation and merging of the output tree in memory (not suitable for very large run...)
 - Some change in the ROOTOuput to fit the requierement of pROOF, using the NPTOptionManager option --proof to activate them

 - Only one read configuration file method
 - lighter code
 - possibility to use TH1F for cross section shoot

 - Now Detector have two method to initialize the root input, one for the Raw data and one for physical data
 - An option ca be given in NPA to specified the input is of physical type

* Identify and correct some bug on the SSSD

   + In NPA, use directly input files from input ROOT file to be analysed 
     if not no input file is given.
   + TAsciiFiles from first input ROOT file in the TChain is taken.

   + when input files are not found, does not exist sytematically
   + it is done manually in Simulation.cc

   + TAsciiFile classes containing input files are now files here and not
     in Simulation.cc anymore

   + search for input files in the $NPTOOL/Inputs/* and local directories
     is now performed in this class
   + this search was done previously in DetectorConstruction.cc and
     PrimaryGeneratorAction.cc files. these files have been modified
     accordingly.
   + If input files are not found, program exits

 - User can no desable all branch except the one concerning the NPA detector in order to improve execution speed

   + exit(1) statement has been added in the DisplayHelp() method from the
     NPOptionManager class

   + 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)

 - A singleton class to make more easy to use NPTool Prog.
 - Class is implemented and tested on one Ananlysis Project
