Dynamic Method Handling

This class handles dynamic methods through the method_missing method

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

Forwards the method to each object in the array. It does no checking to ensure that the receiver can understand the message before sending it. This will return an array of the results of calling each of the other messages.
