Config (Werval API Reference (0.7.5))

```
public interface Config
```
Application Config.
All getters never return null. They will throw a non checked exception depending on the error.

All getters have an Optional counterpart, suffixed Optional that do not throw and return an Optional that is empty if the config is missing or of the wrong type.
