This can be solved by changing docval for __contains__ to allow NoneType by making 'val' optional (there is no straightforward way to allow NoneType without making it optional) or by removing the docval entirely. I decided to remove the docval because it did not seem necessary to mess with the in operator.
Tests are still failing but at least the example in README.md now runs without error.
