synopsis:            metric spaces
description:
  A 'MetricSpace' is a set together with a notion of distance between
  elements. Distance is computed by a function 'dist' which has the following
  four laws:
  .
    (1) __non-negative__: @forall x y. 'dist' x y >= 0@
  .
    (2) __identity of indiscernibles__: @forall x y. 'dist' x y == 0 \<=\> x == y@
  .
    (3) __symmetry__: @forall x y. dist x y == 'dist' y x@
  .
    (4) __triangle inequality__: @forall x y z. 'dist' x z <= 'dist' x y + 'dist' y z@
  .
  See the Wikipedia <https://en.wikipedia.org/wiki/Metric_space article on metric spaces>
  for more details.
