+/// I.e. Rust should throw a compile error, when one field is added, but not a matching function.
+///
+/// What it does:
+///     - Generates a `generate_ci_functions` function, which wraps the specified rust in functions
+///     in lua and exports them to the globals in the context provided as argument.
+///     - Generates a Commands enum, which contains every Camel cased version of the fields.
+///
+/// Every command specified here should have a function named $command_name, where $command_name is the snake cased name of the field.
+///
+/// This function is exported to the lua context, thus it's signature must be:
+/// ```rust
+///    fn $command_name(context: Context, input_string: String) -> Result<$return_type, rlua::Error> {}
+/// ```
+/// where $return_type is the type returned by the function (the only supported ones are right now
