I've started placing unit test in the experimental branch. Please take a look! Feel free to ask me questions!

@iparask start creating unit tests for the code that exists.

@bspitzbart, I pushed a repo called feature/unit_tests and I included there a unit test for one of my functions. You can use it as a template to create unit tests for the non-EnTK files. I can go in and help if you are not sure how to continue.

Thank you @iparask. Just to be sure, the template I should look at is test_image_disc.py, correct?

[iparask]

Yes, that is correct!
