Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *opts, &proc) ⇒ Object (private)

TODO: make it so we fall back to super if action_view can’t handle method. It’s not as easy as ‘elsif api_render? method`, because respond_to gives false for many methods action view can actually handle, like `h`
