    public interface SequenceDistanceMeasurerDouble

    Implement this interface, SequenceDistanceMeasurerDouble, to define a distance metric for sequences. A sequence may have duplicate elements, unlike a Permutation which must have unique elements. Some SequenceDistanceMeasurers may require the pair of sequences to be the same length, while others do not have that requirement. Some SequenceDistanceMeasurers may require the pair of sequences to contain the same set of elements, while others do not have that requirement. Implementations of this interface compute distances that are floating-point valued.

    If your sequences are guaranteed not to contain duplicates, and the pair is guaranteed to contain the same set of elements, and are of the same length, then consider instead using the classes that implement the PermutationDistanceMeasurerDouble interface. Those classes are specifically for distance between permutations of the integers from 0 to N-1.
