  Test cube_surface_distance()

  The mean distance between two random points on the surface
  of a cube can be computed as:
    mu = ( 5 mu_diff + mu_same ) / 6
  where:
    mu_diff = mean distance, points are on different faces
    mu_same = mean distance, points are on same face.

  Using N = 10000 sample points,
  Exact mean distance (diff) = 0.92639
  Exact mean distance (same) = 0.521405
  Exact mean distance        = 0.858893
  Estimated mean distance    = 0.862766
  Estimated variance         = 0.0945837
