/** \class PhotonID
 *
 *  Applies complex photon Id. Reconstructed photon candidtes are first separated into matched and non-matched to gen particles. 
 *  Non-matched pass the "fake" efficiency. Matched photons get further splitted into isolated and non-isolated (user can choose criterion for isolation)
 *  Isolated photons pass the "prompt" efficiency while the non-isolated pass the "non-prompt" efficiency
