class AliMUONRawStreamTrackerHP::AliDspHeader

 \ingroup raw
 \class AliMUONRawStreamTrackerHP
 \brief A high performance stream decoder for muon tracking DDL streams.

 This is the raw stream class which interfaces between the high performance
 core decoder and the AliRawReader class.
 To gain the most out of the decoder, the Next() method which returns batches
 of decoded digit / channel information should be used. That is:
 \code
   const AliBusPatch* Next();
 \endcode

 This decoder tries to implement as similar an interface as possible to
 AliMUONRawStreamTracker where possible. However certain constructs which
 would slow us down too much are avoided.
