The one in unittest doesn't have this feature. However there's
assertApproxEqual defined locally in the test/test_statistics.py package
that does. Since the other is only meant for local use in
test_statistics.py, we should leave it alone. The one in unittest is pretty
bad but widely used; deprecating it won't have any teeth.
