Title: Added FilterPointsPieNatural procedure

This is a variation on FilterPointsPie that changes the behavior. It allows specification of both clockwise and counterclockwise radials. This means that -10, 10 will produce the same pie as 10, -10, -180, 90 will produce the same pie as 180, 450, and 180, 90 will produce the same pie as 90, 180.
