// 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
