TODO: Implement unpacking by detID.
--- Modifications: ------ A.-M. Magnan, 11/03/10: change Counters map to vectors: ------ save space and provide faster access to elements. ------ A.-M. Magnan, 25/02/10: add run number to the event ------ A.-M. Magnan, 13/01/10: change Counters map to be keyed by fedid

Creates the scope mode digis for the supplied FED IDs or detIds and stores event counters.
If FED IDs are supplied (useFedId=true), unpacks all channels found in the cabling with data. If an empty vector of IDs is supplied, it unpacks all it can find in the FEDRawDataCollection.
