// Base class of an object used for the replication 
// (and possibly filtering) of one (or several) AOD branches.
//
// Author: L. Aphecetche (Subatech)
//
// Intended usage is to be able to produce, besides the standard AOD (AliAOD.root)
// some light-weight AODs, by filtering (or skipping completely) the unwanted branches.
// 
// Exemple usage (pseudo-code) :
// 
// AliAODHandler* aodH = AliAnalysisManager::GetAnalysisManager()->GetOutputEventHandler();
//
// AliAODExtension* ext = aodH->AddFilteredAOD("AliAOD.filtered.root","filtered AOD");
//
// ext->DisableReferences();
//  
// ext->FilterBranch("cascades",0x0); // AliAOD.filtered.root will *not* contain the cascades branch
//
//  
// AliAODBranchReplicator* murep = new AliAODMuonReplicator("MuonReplicator",
//                                                           "remove non muon tracks and non primary or pileup vertices",
//                                                           new AliAnalysisNonMuonTrackCuts,
//                                                           new AliAnalysisNonPrimaryVertices);
// ext->FilterBranch("tracks",murep);   // both the tracks and vertices branches 
// ext->FilterBranch("vertices",murep); // will be filtered by the MuonReplicator
//
