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