+// Wrapping class for reconstruction. Allows to produce reconstruction from
+// different steps: from previously produced hits,sdigits, etc. Each new reconstruction
+// flow (e.g. digits, made from them RecPoints, subsequently made TrackSegments,
+// subsequently made RecParticles) are distinguished by the title of created branches. One can
+// use this title as a comment, see use case below.
+// Thanks to getters, one can set
+// parameters to reconstruction briks. The full set of parameters is saved in the
+// corresponding branch: e.g. parameters of clusterizer are stored in branch
+// TreeR::AliPHOSClusterizer with the same title as the branch containing the RecPoints. // TTree does not support overwriting, therefore one can not produce several
+// branches with the same names and titles - use different titles.
+//
+// Use case:
+//
+// root [0] AliPHOSReconstructioner * r = new AliPHOSReconstructioner("galice.root")
+// // Set the header file
+// root [1] r->ExecuteTask()
+// // Make full chain of reconstruction
+//
+// // One can specify the title for each branch
+// root [2] r->SetBranchFileName("RecPoints","RecPoints1") ;
+//
+// // One can change parameters of reconstruction algorithms
+// root [3] r->GetClusterizer()->SetEmcLocalMaxCut(0.02)
+//
+// // One can specify the starting point of the reconstruction and title of all
+// // branches produced in this pass
+// root [4] r->StartFrom("AliPHOSClusterizer","Local max cut 0.02")
+// // means that will use already generated Digits and produce only RecPoints,
+// // TS and RecParticles
+//
+// // And finally one can call ExecuteTask() with the following options
+// root [5] r->ExecuteTask("debug all timing")
+// // deb - prints the numbers of RecPoints, TrackSegments, RecParticles
+// // deb all - prints in addition list of RecPoints, TrackSegments, RecParticles
+// // timing - prints benchmarking results
