   Monte Carlo signal definition:
      Leg #1  <-- Mother #1  <--  Grandmother #1
                      |
      Leg #2  <-- Mother #2  <--  Grandmother #2
  
   For every leg, mother or grand-mother, a PDG code and a source can be specified.

   1.) For the PDG codes, the PYTHIA standard is used. 
   A few non-existent PYTHIA codes are used to select more than one PYTHIA code. All these are described below
   and implemented in AliDielectronMC::ComparePDG() function:
      0 - default, accepts all PYTHIA codes
    100 - light unflavoured mesons in the code range 100-199
    200 -        --"--                               200-299
    300 - strange mesons in the code range           300-399
    400 - charmed mesons in the code range           400-499
    401 - open charm mesons (all D and D* mesons)    400-439
    402 - open charm mesons and baryons together     400-439, 4000-4399
    403 - all charm hadrons (mesons and baryons)     400-499, 4000-4999
    500 - beauty mesons in the code range            500-599
    501 - open beauty mesons                         500-549
    502 - open beauty mesons and baryons             500-549, 5000-5499
    503 - all beauty hadrons                         500-599, 5000-5999
   1000 - light unflavoured baryons in the code range 1000-1999
   2000 -        --"--                                2000-2999
   3000 - strange baryons in the code range           3000-3999
   4000 - charmed baryons in the code range           4000-4999
   4001 - open charm baryons                          4000-4399
   5000 - beauty baryons in the code range            5000-5999
   5001 - open beauty baryons                         5000-5499

   2.) If the exclusion flags are turned ON then the PDG codes required and the conventional codes described above
       are used to exclude the selected particles. 

   3.) If the selection of both charges is switched ON then the PDG codes act on both particles and anti-particles.

   4.) Particles sources implemented:
     1. Primary   - particle originating in the physics event
     2. FinalState- stable(final state) particles which reach the detector -> according to AliStack::IsPhysicalPrimary() 
     3. Direct    - primary particle which has no mother (e.g. J/psi's added to pythia MC events via generator cocktails,
                    particles generated in a sudden freeze-out in thermal models, initial state particles)
     4. Secondary - particle created during the GEANT propagation due to interaction of final state primaries with the material

   5.) The 2 legs can originate from the same or different mother particles. This can be specified via the SetMotherRelation()
       method call.

   6.) The filling of the pure MC step can be switched on using SetFillPureMCStep() method call. This should be used
       with care since at the pure MC information level there is no cut applied and for abundant particles the combinatorics
       can be very high.
