  Python version: 3.6.9
  Test square_surface_distance()

  The mean distance between two random points on the surface
  of a square can be computed as:
    mu = ( 3 mu_diff + mu_same ) / 4
  where:
    mu_diff = mean distance, points are on different sides
    mu_same = mean distance, points are on same side.

  Using N =  10000  sample points
  Exact mean distance (diff) =  0.8690090552745344
  Exact mean distance (same) =  0.3333333333333333
  Exact mean distance        =  0.7350901247892342
  Estimated mean distance    =  0.7339239613542828
  Estimated variance         =  0.1268039241633685
