 * Interface for <a href="http://en.wikipedia.org/wiki/Edit_distance">Edit Distances</a>.

 * <p>
 * A edit distance measures the similarity between two character sequences. Closer strings
 * have shorter distances, and vice-versa.
 * </p>
 *
 * <p>
 * This is a BiFunction&lt;CharSequence, CharSequence, R&gt;.
 * The <code>apply</code> method
 * accepts a pair of {@link CharSequence} parameters
 * and returns an <code>R</code> type similarity score.
 * </p>
 *
 * @param <R> The type of similarity score unit used by this EditDistance.
