Detailed Description

Associate clusters to each track based on its extrapolation to the calo.

This alg reads in a CaloExtensionCollection corresponding to a TrackParticleContainer. It then decorates each TrackParticleContainer with a vector<EL<CaloCluster>> containing the clusters close enough (DeltaR property) w.r.t CaloExtension corresponding to the track. Optionnaly tracks are also decorated with a const Trk::TrackParameters* obtain from caloExtension->caloEntryLayerIntersection().

Note: In earlier versions this alg was creating 2 maps a xAODAssociations/TrackParticleClusterAssociationContainer and a Rec::ParticleClusterAssociation and was using ParticleCaloClusterAssociationTool to retrieve the extrapolation and perform the clusters association. All of this was suppress or replaced in order to simplify the procedure.
