 ** @brief Task class for associating digis to events
 ** @author Volker Friese <v.friese@gsi.de>
 ** @since 13.03.2020
 ** @version 1.0
 **
 ** The event association uses MC truth (CbmMatch of CbmDigi).
 ** It operates within one time slice; splitting of events between
 ** time slice is not treated.
 **
 ** Using CbmEventStore (storable events).
