20// This class provides access to PHOS/EMCAL digits in raw data.
21//
22// It loops over all PHOS/EMCAL digits in the raw data given by the AliRawReader.
23// The Next method goes to the next digit. If there are no digits left
24// it returns kFALSE.
25// Several getters provide information about the current digit.
26// usage:
27// AliRawReader *reader = AliRawReader::Create(fileName);
28// AliCaloRawStreamV3 *stream = new AliCaloRawStreamV3(reader,calo);
29// while (reader->NextEvent())
30// while (stream->NextDDL())
31// while (stream->NextChannel()) ...
