albocycline example tests merge request

[vvoelz]

For testing, I modified the notebook so the number of steps is smaller. This way, people seeing/running it for the first time aren't waiting 2 min just to see if it works. There's a comment saying the number should be increased for production.

Then I added a testing script called test_albocycline.py that can be tested (along with all other future tests) like this:

(py37) vv@cst14330 albocycline % pytest -v

The test_albocycline.py script converts the Jupyter notebook to a standalone script, and then tries to run it (by importing it). I had to add a try/except loop to the ipython magic commands because they will only run using ipython, and the testing scripts need to be run on the standard python install.
