- properly deal with root install where rootcint is not
          available. e.g. mac port install

        - The NPMULTITHREADING flag is now pass to rootcint when
          building the dictionnaries
        - This is done by generating the macro via cmake

! Adding a new folder TrackReconstruction for Tracking algorithm

        - The command testing rootcint was left to debug mode leading to
          compilation failure

        - check rootcint binary is present and issue error message if
          not
        - Error message gives hint of the problem root and suggest
          solution

  - appear to be a missing include in the dictonnary generation

  - now all detector are within a Detectors Folder
