// Implementation version 1 of the clusterization algorithm
// Performs clusterization (collects neighbouring active cells) and
// unfolding of the clusters with several local maxima.
-// results are stored in TreeR#, branches PHOSEmcRP (EMC recPoints),
-// PHOSCpvRP (CPV RecPoints) and AliPHOSClusterizer
+// results are stored in TreeR
//
//*-- Author: Yves Schutz (SUBATECH)
-// Modif:
-// August 2002 Yves Schutz: clone PHOS as closely as possible and intoduction
-// of new IO (à la PHOS)
+//-- Gustavo Conesa (LPSC-Grenoble), move common clusterizer functionalities to mother class
