//////////////////////////////////////////////////////////////////////////////
// Clusterization class. Performs clusterization (collects neighbouring active cells) and
// unfolds the clusters having several local maxima.
// Results are stored in TreeR#, branches EMCALTowerRP (EMC recPoints),
// EMCALPreShoRP (CPV RecPoints) and AliEMCALClusterizer (Clusterizer with all
// parameters including input digits branch title, thresholds etc.)
-// This TTask is normally called from Reconstructioner, but can as well be used in
-// standalone mode.
-// Use Case:
-// root [0] AliEMCALClusterizerv1 * cl = new AliEMCALClusterizerv1("galice.root")
-// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
-// //reads gAlice from header file "..."
-// root [1] cl->ExecuteTask()
-// //finds RecPoints in all events stored in galice.root
-// root [2] cl->SetDigitsBranch("digits2")
-// //sets another title for Digitis (input) branch
-// root [3] cl->SetRecPointsBranch("recp2")
-// //sets another title four output branches
-// root [4] cl->SetTowerLocalMaxCut(0.03)
-// //set clusterization parameters
-// root [5] cl->ExecuteTask("deb all time")
-// //once more finds RecPoints options are
-// // deb - print number of found rec points
-// // deb all - print number of found RecPoints and some their characteristics
-// // time - print benchmarking results
