// Class that contains the algorithm for the reconstruction of jet, cone around leading particle
+// 1)Take the prompt photon found with AliAnaGammaDirect,
+// 2) Search for the highest pt leading particle opposite to the photon within a phi, pt window
+// 3) Take all particles around leading in a cone R with pt larger than threshold and construct the jet
+//
// Class created from old AliPHOSGammaJet
// (see AliRoot versions previous Release 4-09)
