// 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
