com.espertech.esper.collection.RollingEventBuffer
Event buffer of a given size provides a random access API into the most current event to prior events up to the given size. Oldest events roll out of the buffer first.
Backed by a fixed-size array that is filled forward, then rolls back to the beginning keeping track of the current position.

     * @param maxPriorIndex is the highest prior-event index required by any expression
