Detailed Description

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.
