Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

You can def things in controller and use them as macros inside actions But these defs. live in the TransitionCompilerController instance and we need to delegate these calls to the controller that are not available in the action
