public class CarryCounter
extends Rename
implements VisualComponent, EventLabels

A carry counter suitable for building a multi-digit counter. There are two cases, a single-digit carry counter that reports overflow when it reaches its maximum value, and a carry counter build from two existing carry counters.

To chain two carry counters, the overflow of the less significant digits (c1) increments the more significant digits (c2).
