#dotenv_safe
Similar to this dotenv package:
https://github.com/joho/godotenv
This adds an assurance layer. It demands that particular environment variables be set and panics if they aren't.
It uses the same paradigm as this node package:
https://www.npmjs.com/package/dotenv-safe
Which is that required env variables are contained in an example.env file in the project's root.
