We're almost there, good job with such a big first contrib!

I think that if you address the three inline comments that I've left that require changes, the next version should be ready for merging :)

Although this changes the original test a bit, considering that all unittests are still passing, my assumption is that this is a valid representation, still.

Leaving this note here to set the expectations, in case someone else sees and asks for this to be changed (but I don't think anyone will, since tests are passing)
