Dynamic Method Handling

This class handles dynamic methods through the method_missing method

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

Used to create attribute accessors on the fly.

On first call of a missing method a method is generated to avoid the missing lookup next time, this should be faster for repeated lookups of the same method, e.g. reg
