* Changes relative to V.1.7b
   - LHE files where not processed correctly (empty Analysis/Trigger trees). 
     Now LHEFParticle derives from TRootC::GenParticle as it should.
   - additional data in the logfile : all names of used input files 
     (input event files, detector card, trigger card, beam files, particle table)
   - it is now possible to read "delphes root files" as an input for Delphes (GEN tree)

 \-----------------------------------------/
  Bug fixes for V.1.7------
* Changes relative to V.1.7
   - small typos in "cout" removed
   - Nevents implemented in DetectorCards
   - bug removed in bad inputfile type identification (".hep" vs ".lhe")
   - bug removed with calotowers(BinEtaPhi) : now use the middle of the 
      tower and not its lower edge in eta and in phi
   - bug removed for compilation error with FROG (genMakefile) : 
      the options  -Dmacos/-Dlinux/-Dwindows are automatically added 
      in CXXFLAGS when required
   - 3 bugs removed in BField (omega*gammam ; units in r ; z_max). 
      Bfield validated.
   - new headers in each file with full references

 /-----------------------------------------\
| 12 March 2009: release Version1.5         |
 \-----------------------------------------/

 * Changes relative to V.1.4beta:
    - implementation of the energy flow
        - calotowers are first merged then smeared
        - photons are based on these calotowers: conservative approach
        - electrons are separately smeared according to the calotower
          resolution.
    - new: list of calorimeters ; CaloUtil added
    - new: constants moved from SmearUtil.* to D_Constants.* 
    - new: GenParticle class
    - ParticleUtil changed into D_Particle
    - tracks and Taujets have now a charge
    - output available as a LHCO (text) data file, in option
    - extensive test and correction of the Bfield
        - using now an exact computation, assuming solenoidal field
        - about 20% faster than iterative approach
    - charged lepton isolation: IsolPt available 
    - data cards
         - default names have been changed
         - more parameters for more flexibility
        

 /-----------------------------------------\
| 09 February 2009: release Version1.4beta  |
 \-----------------------------------------/

 * Changes relative to V.1.3beta:
    - new overal header and program output to screen.
    - new trigger cards ATLAS and CMS-like
    - new detector card ATLAS oriented
    - New input parameters in the datacard for very forward detectors
    - Modification of the Resolution.cpp code to run on the output of Delphes directly
    - #include statements have been cleaned ; more include paths 
      in the compilation, leading to easier #include statements.
    - extensive use of 'valgrind' for the search for memory leaks.
      No more explicit leak is in the code. The only leaks left are
      related to ROOT, to mcfio dependecy and to Hector.
      This implied the systematic addition of copy-constructor, 
      operator= and correct destructors in Delphes classes
    - update of the BField simulation; still in the case of B = Bz only
    - JetsUtil* files renamed to JetsUtil*
 * Private modifications in dependencies
    - memory leaks removed in FROG (applied on Frog v1.106)
    - systematic change of by-value parameters to "by-const-reference" 
      in Hector (applied on Hector v1.3.1)

 /-----------------------------------------\
|  29 January 2009: release Version1.3beta  |
 \-----------------------------------------/

 * Changes relative to V.1.2beta:
    - Cleaning of non necessary comments 
    - Removal of the minimal transverse momentum applied on tracks and calotowers when the magnetic field is simulated 
    - Correction of the FROG interface 
    - Addition of a new standalone code to run FROG on the analysis output ROOT file 
    - New magnetic field algorithm: exact computation in case of magnetic field having a Bz component only 
    - Time performance monitoring 
    - Cleaner tarball 
 * Known limitations of this release are:
    -Work is currently being done on eta/phi variables leading to some uncertainties on these quantities when the magnetic field is switched on



 /-----------------------------------------\
| 18 December 2008: release Version1.2beta  |
 \-----------------------------------------/

 * Changes relative to V.1.1beta:
    - Reconstruction of jets: the number of defined cell 
      towers is now correctly taken into account by the 
      jet algorithms 
    - Input for jet reconstruction: calotowers instead 
      of generated particles 
    - Input datacard parameters now taken into account by
      the jets, very forward detectors, magnetic field 
      propagation steps 


 /-----------------------------------------\
| 13 December 2008: release Version1.1beta  |
 \-----------------------------------------/

 * Changes relative to V.1.0beta:
    - Addition of a class that run the FROG code on the 
      reconstructed events to perform visualisation of 
      events and detector geometry 
    - Addition in the datacard of flags to switch on/off 
      magnetic field, very forward detectors, trigger and FROG 
      running 


 /-----------------------------------------\
| December 2008: release Version1.0beta     |
 \-----------------------------------------/

 * First available release
 * Includes 
    - Classes that perform 
        - Conversion of HepMC, LHE and root file conversion 
        - Simulation of charged particles into a magnetic field 
        - Smearing of the energy of undecaying particles 
          according to some applied resolution functions 
        - Reconstruction of jets using the FastJet package

        - Application of a trigger selection

    - An input trigger datacard to apply a selection of events 
      with user defined trigger bits (e.g. data/trigger.dat). 
    - An example of user code to run on the output root file of 
      the DELPHES program.
 * Known limitations of this release are 
    - Imperfect reconstruction of jets: the number of defined cell 
      towers not correctly taken into account by the jet algorithms. 
    - Reconstruction of very forward detectors not entirely completed.
