class AliAnaPi0: public AliAnaCaloTrackCorrBaseClass

 Class to collect two-photon invariant mass distributions for
 extracting raw pi0 yield.
 Input is produced by AliAnaPhoton (or any other analysis producing output AliAODPWG4Particles),
 it will do nothing if executed alone

Do some MC checks on the origin of the pair, is there any common ancestor and if there is one, who?
Adjusted for Pythia, need to see what to do for other generators.
Array of histograms ordered as follows: 0-Photon, 1-electron, 2-pi0, 3-eta, 4-a-proton, 5-a-neutron, 6-stable particles,
 7-other decays, 8-string, 9-final parton, 10-initial parton, intermediate, 11-colliding proton, 12-unrelated
