* An interface for classes which measures the degree of similarity between two {@link Geometry}s.

* Higher measures indicate a great degree of similarity.
* A measure of 1.0 indicates that the input geometries are identical
* A measure of 0.0 indicates that the geometries
* have essentially no similarity.
* The precise definition of "identical" and "no similarity" may depend on the
* exact algorithm being used.
