Adding an example file to run scheduler runs/tests

- Initial script to hopefully store any kind of test script that can run through the scheduler through its development
- This may turn into a test script. It may turn into multiple example files...not sure yet
- This is now the second working example of what's currently included (the first is what's at the bottom of scheduler.py)
