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/// root > AliRawReaderFile rawReader ;
28/// root > AliCaloRawStream input(&rawReader) ;
29/// root > while (input.Next()) .....
30///
31///Modification: Class exported from PHOS to be used by EMCAL and PHOS
