 *  EVGEN/AliGenEMCocktail.cxx (& .h) is the class that generates the cocktail following the muon example.
 *  EVGEN/AliGenEMlib.cxx (& .h) is the class that contains the kinematic distributions of the sources, also following the muon example. At the moment, it contains
    only one pT distribution plus mT scaling. In the near future I'll extend this class with further parameterizations. Also, I'll add the functionality to set
    parameters by proper set methods (instead of the hard-wired parameters as used currently in all of the similar lib classes).
 *  EVGEN/libEVGEN.pkg and EVGEN/EVGENLinkDef.h have been modified to include the two new classes.
 *  EVGEN/AliDecayer.h has been modified by adding three new decay modes (kElectronEM, kDiElectronEM, and kGammaEM) between which one can select in the cocktail
    class.
 *  EVGEN/AliGenMC.cxx has been modified such that it "knows about" the three new decay modes in EVGEN/AliDecayer.h
 *  PYTHIA6/AliDecayerPythia.cxx has been modified accordingly. Here, the corresponding particle decays are forced depending on the selected decay mode.
 *  FASTSIM/fastGenEMCocktail.C is an example macro to generate a single electron cocktail.
