> KMeans currently on the map-side calculates the distance between a set of
> seeds and all other vectors. It would be handy to have a generalization of
> this that, given a set of vectors that fits in memory (the seeds) and other
> points, emit <seed id, other id, distance> according to the distance measure.
> This is similar to the RowSimilarityJob, but much simpler and not as general
> purpose.
