# AttrAccessorBlock
#
# This module is to be "extended" (not included) into a class
# Then just invoke the "attr_accessor_block" method, like you would with "attr_accessor"
# This will enable you to make use of "block notations" and "instance_eval" to create "prettier"
# and more "readable" attribute setters.
#
#  class Example
#    extend AttrAccessorBlock
