- This adds support for reading configurations from a three layer hierarchy: 1. User provided TOML 2. Install root TOML 3. Code defaults - We add some code to support plugin configurations via the ConfigurationLoader. Each plugin can provide a struct with an accompanying id that gets used to parse the scoped section of the TOML.
