Investigate using dilate for surface dice

[pchlap]

Nice work! I'm not sure if timing is really an issue, but the distance maps can take a while to compute so an alternative could be to dilate each contour with sitk.BinaryDilate(a_contour, tau_in_voxel_units)

Another point to discuss: there is also a function sitk.BinaryDilate which seems to do something very similar to sitk.BinaryContour - but with different output!
