20 // Implementation version 1 of the clusterization algorithm
21 // Performs clusterization (collects neighbouring active cells) and
22 // unfolding of the clusters with several local maxima.
23 // results are stored in TreeR#, branches PHOSEmcRP (EMC recPoints),
24 // PHOSCpvRP (CPV RecPoints) and AliPHOSClusterizer
