> This is an idea to help optimize cases where a user asks for a specific TimeStamp or TimeRange in their query.
> If specifying a TimeRange, we are unable to use any kind of bloom to determine whether we need to open every file or not.  If we knew the max/min timestamps in each file, we could use that information to prevent opening files we know do not contain any versions from the query's TimeRange.
