const AliParticleContainer tracks,
const AliClusterContainer clusters = nullptr,
Double_t vertexpos = nullptr 

Run iterative declustering of the jet.

Reclusters jet with the Cambridge/Aachen algorithm and traverses the cluster tree. For each splitting the lund plane parameters defined in AliLundPlaneParamters are evaluated and added to the splitting container. The declustering is done always on the harder subjet until the abort condition (no more child subjets or subjet > hard cutoff) is fulfilled. Needs track/particle/cluster containers in order to have acces to the jet constituents.

jetJet to be tested
tracksContainer with tracks / particles (optional only in case of neutral jets)
clustersContainer with calorimeter clusters (optional, for det. level full jets)
vertexposPosition of the primary vertex (optional, mandatory in case a cluster container is set)
Container with lund plane parameters for each splitting
