module Base
# This module adds hashing capabilities to form elements.
# Do not include this module in your classes. It is already
# included in the base_element class.
#
# Sample usage:
#
# class MyField
# attr_accessor :param1, :param2
# hashable :param1, :param2
# ...
# end
#
# Any instance of MyField class will have the "to_hash" method
# that will contain only the accessor/reader params defined in
# the hashable macro.
