--------------------------------------
[~erans], would you prefer that this go in commons-geometry?

> We should add a new class to commons-numbers-core that encapsulates
> configurable strategies for comparing doubles. This is required for
> GEOMETRY-11. Here is what I'm picturing:
> {code:java}
> // abstract class for the general concept of comparisons
> public abstract class DoublePrecisionContext implements Comparator<Double> {
> public abstract boolean equals(double a, double b);
> public int compare(double a, double b) { /* ... */ }
> public int compare(Double a, Double b) { /* ... */ }
> }
> // ...
> // concrete class implementing a specific strategy
> public class EpsilonUlpDoublePrecisionContext extends DoublePrecisionContext {
> public EpsilonUlpDoublePrecisionContext(double eps, double maxUlps) { /*
> ... */ }
> @Override
> public boolean equals(double a, double b) { /* ... */ }
> } {code}
