49 * Class for running clusterization for PHOS in HLT. It takes digits as input and
50 * gives reconstruction points as output.
52 * The component has the following component arguments:
53 * -clusterthreshold The energy threshold for starting a new rec point
54 * -energythreshold The energy threshold for including a digit in a
