Dynamic Method Handling

This class handles dynamic methods through the method_missing method

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

A bard.rb may use DSL contributed by plugins. When the owning plugin is loaded it defines a real method that wins over this; otherwise we tolerate the declaration as a plain attribute so the file still parses — notably server-side, where bard-cli is absent.
