// Class for the analysis of high pT pi0 event by event\r
// Pi0 identified by one of the following:\r
//  -Invariant mass of 2 cluster in calorimeter\r
//  -Shower shape analysis in calorimeter\r
//  -Invariant mass of one cluster in calorimeter and one photon reconstructed in TPC (in near future)\r
