Python version of survey formatting

[clpetersonucf]

This file doesn't belong in the django Materia repo, but I wanted to maintain a reference to it when it's implemented in this widget: https://github.com/ucfcdl/Materia/blob/70ee3a7e7d136c26bbbbb7edcb5a65eeebb47c58/app/util/simple_survery_exporter.py

Not that it utilizes references to SessionLogger, which will need to be reworked. That util class is being removed.
