/// This class provides access to MUON digits in raw data.
///
/// It loops over all MUON 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(under develpment).
+/// The Next method goes to the next local response. If there are no local response left
+/// it returns kFALSE.
/// It can loop also over DDL and store the decoded rawdata in TClonesArrays
/// in payload class.
