Initial starter notebooks

Verify auto grading working locally and also on Colab.

• Document Requirements.txt and create readme
• Create a copy of the notebooks that has testing code in notebook. Ensure the module file can be imported and run to do the grading for all 3 notebooks.
• Create a separate copy which doesn't have the 'notebook_append' code and have a script which converts the .ipynb to .py and then concatenates the notebook_append code. For example, this will combine the two files. cat lab_1_3.py notebook_append.py >> lab_1_3_grade.py
• Execute both scenarios via external scripts for all notebook files.
• Have travisCI execute the module.
