Created Jun 4, 2009
Allows you to require parameters from hashes in your methods
View attribute_support.rb
# A module which adds support for attribute validation and requirements
# directly to the Hash object in Ruby. Very useful for methods which
# require a ton of attributes.
#
# ==== Example Usage
#
# require 'attribute_support'
#
# class Klass
# def renew_domain(attributes = {})
