// This TTask performs digitization of Summable digits (in the PHOS case it is just
// the sum of contributions from all primary particles into a given cell).
// In addition it performs mixing of summable digits from different events.
+// The name of the TTask is also the title of the branch that will contain
+// the created SDigits
+// The title of the TTAsk is the name of the file that contains the hits from
+// which the SDigits are created
//
// For each event two branches are created in TreeD:
