Fix tox.ini (works for me now)

I think it may have been the PYTHONPATH, it's not needed.

Also, since both test environments were the same, I as able
to reduce this to just one section for both python versions.

Also, fixed the README.rst formatting, examples were on one
line/wrapping funny.
Fixed two things I missed earlier

Forgot to remove :py27 from [testenv]

After that, I noticed the reason it was blowing up in python 3,
which was the end of the error output, was because wsgiref from
the requirements.txt actually failed to install on python3.

After closer inspection, it appeared wsgiref was not used anyway,
so I removed it from the requirements.txt

Things are working now, the tests are just not working on
python 3, but since you are switching to nose in another
branch anyway, I will leave that upto you.
Commit a version of requirements used with the 2.7 virtualenv while I fiddle around with a 3.x virtualenv
A version of requirements.txt for use with the 3.x virtualenv
Add future to 3.x virtualenv
A set of changes to make the code run cleanly under 3.4
Working version ! Running tox produces good test results for both environments . ./venv3/bin/activate Unfortunately actually running the code doesn't work but that's what I'm going to figure out next
