I'll be fixing the docs build in in a #861. Hold of working on this or fixing the docs.

[germa89]

@akaszynski in my case the building was failing because of format issues (forgot to backscape).

[germa89]

I'm still investigating the issues about the "-1".

Nice work, and great unit testing.

Made several changes, all style except for adding autopep8 to our test requirements so we can test if autopep8 works.

Thank you Alex.

Apologies for the style errors, I should be more careful with those.
