//  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 produced SDigits, Digits etc.
//             // deb all - prints in addition list of made SDigits, digits etc.
//             // timing  - prints benchmarking results

7acf6008	53	//

7acf6008	56	// // deb - prints the numbers of produced SDigits, Digits etc.
