/// \class AliMUONRawStreamTriggerHP
///
/// Implementation of a streamer interface to the high performance trigger decoder.
/// This is the raw stream class which interfaces between the high performance
/// core decoder for MUON trigger chambers and the AliRawReader class.
/// To gain the most out of the decoder, the Next() method should be used,
/// for example:
/// \code
///   AliMUONRawStreamTriggerHP* rawStream;  // assume initialised
///   const AliMUONRawStreamTriggerHP::AliLocalStruct* localStruct;
///   while ((localStruct = rawStream->Next()) != NULL)
///   {
///      // Do something with localStruct here.
///   }
/// \endcode
///
/// This decoder tries to implement as similar an interface as possible to
/// AliMUONRawStreamTrigger where possible. However certain constructs which
/// would slow us down too much are avoided.
///
