A knob is a wrapper for an environment variable. It can:
- Read and write an environment variable
- Make sure it is of the expected type
- Validate a value is good.
knobs will search for a nominated environmental file (default .env) and load that into the environment. A knob is type aware, configured from the environment and its value can be persisted to ease the creation of configuration files.
