Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *arguments) ⇒ Object

Call perform_later on an ActiveJob class corresponding to an undefined action method name. Most of the work here is done in the Performer class, which takes care of discoevering whether the method passed in corresponds to a given job or whether we should just delegate back to ActiveRecord::Base. This method will prevent a new Perfomer class from being instantiated for every method call by using a guard clause to check whether the method is an action method before proceeding on further checks.
