20/// This class provides access to ZDC digits in raw data.
21///
22/// It loops over all ZDC 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/// Getters provide information about the current digit.
