-// Class that contains the algorithm for the analysis of particle - hadron correlations\r
-// Particle (for example direct gamma) must be found in a previous analysis \r
-//-- Author: Gustavo Conesa (INFN-LNF)\r
-\r
-// Modified by Yaxian Mao:\r
-// 1. add the UE subtraction for corrlation study\r
-// 2. change the correlation variable\r
-// 3. Only use leading particle(cluster/track) as trigger for correlation (2010/07/02)\r
-// 4. Make decay photon-hadron correlations where decay contribute pi0 mass (2010/09/09)\r
-// 5. fill the pout to extract kt at the end, also to study charge asymmetry(2010/10/06) \r
-// 6. Add the possibality for event selection analysis based on vertex and multiplicity bins (10/10/2010)\r
-// 7. change the way of delta phi cut for UE study due to memory issue (reduce histograms)\r
