9// Implementation version 1 of the clusterization algorithm
10// Performs clusterization (collects neighbouring active cells) and
11// unfolding of the clusters with several local maxima.
12// results are stored in TreeR#, branches PHOSEmcRP (EMC recPoints),
13// PHOSCpvRP (CPV RecPoints) and AliPHOSClusterizer
