Add compatibility for Python2

[fristonio]

In the rewrite, few features are evaluated in python3 and not tested for python2. It would be great if we can add backward compatibility for python2 to Origami-lib.

Before this try resolving the issue to add logging support for Origami-Lib

Hey @jjmachan sorry I missed the comment. You can first try to set up the project locally and play with it a bit. You will have to explore the code to find the components which are not python2 compatible. Let me know if you don't understand something in the code. :)
