+/// This class provides access to EMCAL digits in raw data.
+///
+/// It loops over all EMCAL digits in the raw data given by the AliRawReader.
+/// The Next method goes to the next digit. If there are no digits left
+/// it returns kFALSE.
+/// Several getters provide information about the current digit.
+/// usage: 
+/// root > AliRawReaderFile rawReader(#event) ; 
+/// root > AliPHOSRawStream input(&rawReader) ; 
+/// root > while (input.Next()) .....
