Python2 compatibility

When I execute the example, I get an error:

Wikitables is written in Pyhton3.
I too got the same error in Python2 possibly because in python3 strings are sequence of unicode characters whereas in python2, strings are sequence of ascci characters.

I got the same error, but it went away when I ran with python3.

Wikitables is indeed a Python3 library; however, I hope to have Python2 support available soon.

Please edit the readme to prevent more disappointment while we wait for a port. BTW thanks for the great idea, wiki parsing has never been easier.

[bcicen]

@Hunter-Github good point; I've added a note to the readme for the time being.

Fixed in #6, but keeping this open to track other Py2 compat issues

Updates for Python2 compatibility have been included in the latest release.
