Detailed Description

This class provides a hashing algorithm for bmqt::MessageGUID. At the time of writing, this algorithm was found to be approximately 4x faster than the default hashing algorithm that comes with bslh package. Performance-critical applications may want to use this hashing algorithm instead of the default one.
