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