Created a new User, Experiment, and ExperimentSession and tested that all the default fields were set to their correct defaulted values. Additionally, I created an experiment, experiment session, and user fixture and tested that the fields in the fixtures were correctly set.
Modified fixture files to include valid data for testing for experiments, experiment sessions, and users.
