Created June 4, 2009 16:20
Allows you to require parameters from hashes in your methods
# A module which adds support for attribute validation and requirements
# directly to the Hash object in Ruby. Very useful for methods which

#
# require 'attribute_support'
#
# class Klass
# def renew_domain(attributes = {})
