Dynamic Method Handling

This class handles dynamic methods through the method_missing method

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

Hacky way to avoid having to define a method for each of the config properties. Here just for fun and to make it easier to play around with the code. This causes undesireable downstream effects, i.e. calling ‘respond_to?(:anything)` would return true, which it’s fine in this codebase/project
