Dynamic Method Handling

This class handles dynamic methods through the method_missing method

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

> Search for the translate pattern at the beginning of the method,

if it is found, look for the translation based on the end of the method name and the argument that is passed to it.
