 * \ingroup BeamDataUtil
 *
 * \brief Pull out not recently seen RawBeamMonBlocks from Mom.
 *
 * Unfortunately there was a period of time where multiple callbacks
 * were set in the bdp-server.  This resulted in almost two weeks of
 * data taking where there will be multiple spills in mom when the
 * data is read back.  This class tries to clean things up as best as
 * possible.  It does this by remembering the last N VldTimeStamps and
 * returning only those RawBeamMonBlocks that have VldTimeStamps that
 * are not near any of the last ones.
