Port the code for Python 2.7 #3
Description
Presently, all of our codebase is complaint with Python3.5. Although, there's a high probability that a lot of people might have to use it with Python2.7.
Create a separate branch for this, so that we can also have options to provide two different versions for the textbrew(2.7 and 3.5).
Maybe you can use, something like https://pypi.python.org/pypi/3to2.
