A StatsListener that cycles over a given period, and once each period, grabs a snapshot of the
given StatsCollection and computes deltas since the previous timeslice. For example, for a
one-minute period, it grabs a snapshot of stats at the top of each minute, and for the rest of
the minute, reports these "latched" stats.
