Metric

object Metric extends Serializable

A Metric[V] m is a function (V, V) => Double that satisfies the following properties:

1. m(v1, v2) >= 0 2. m(v1, v2) == 0 iff v1 == v2 3. m(v1, v2) == m(v2, v1) 4. m(v1, v3) <= m(v1, v2) + m(v2, v3)

If you implement this trait, make sure that you follow these rules.
