Added 4 advanced scenarios to the README to show how to use the new functions. Also updated sample.py to show an error message and exit rather than show a Traceback when there are Environment variables that are missing. I was able to replicate #1 with no environment variables set and with this change I no longer get a Traceback. Setting env variables works successfully.
