pip install failure ReadtheDocs

[bjbford]

requirements.txt:

sphinx
sphinx_rtd_theme
recommonmark
sphinx-markdown-tables

It seems that this package it not supported by readthedocs.

I believe the issue is from the dependency of python3.5 as it installed fine on my machine, but not the readthedocs server. (The same install error occurred on a colleagues machine with only python3.4) I tried added markdown to the requirements.txt file, however I received the same error.

pip install -r requirements.txt:

    ----------------------------------------

Maybe this code should be ported to Python 2.7?

Update:
In the ReadtheDocs project Admin page, under Advanced Settings. You can change the Python Interpreter from CPython 2.x (default) to CPython 3.x. This resolved the install error.

I still think revising the code to support Python 2.7 would be a good idea, considering Sphinx works with Python 2.7.

Seems like there was an issue with a circular import during setup. Only appeared using python 2. At any rate, it should be fixed in v0.0.7.
