// 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
