public class MeterRDFCylinder
extends MeterRDF

MeterRDF sublcass that properly calculates the RDF for the Piston/Cylinder apparatus. Including all pairs would yield a very non-bulk RDF since atoms near the wall have open space next tho them. To account for this, if "padding" is the collision radius + RDF cutoff, then the RDF calculation includes all pairs where both are a distance "padding" away from all walls and half the pairs where only one is a distance "padding" away from all walls. The RDF is normalized to account for this.
