// Clusterization class. Performs clusterization (collects neighbouring active cells) and

// Use Case:
-// root [0] AliPHOSClusterizerv1 * cl = new AliPHOSClusterizerv1("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 [0] AliPHOSClusterizerv1 * cl = new AliPHOSClusterizerv1(<pointer_to_phos_geometry_onject>)
+// root [1] cl->Digits2Clusters(digitsTree,clusterTree)
+// //finds RecPoints in the current event
// 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->SetEmcLocalMaxCut(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
