18// Class that contains the algorithm for the reconstruction of jet, cone around leading particle
19// The seed is a backward particle (direct photon)
20// 1)Take the trigger particle stored in AliAODPWG4ParticleCorrelation,
21// 2) Search for the highest pt leading particle opposite to the photon within a phi, pt window
22// 3) Take all particles around leading in a cone R with pt larger than threshold and construct the jet
23//
24// Class created from old AliPHOSGammaJet
25// (see AliRoot versions previous Release 4-09)
