module Spree
module DisplayMoney
##
# Takes a list of methods that the base object wants to be able to use
# to display with Spree::Money, and turns them into display_* methods.
# Intended to help clean up some of the presentational logic that exists
# at the model layer.
#
#
# ==== Examples
# Decorate a method, with the default option of using the base object's
# currency
#
# extend Spree::DisplayMoney
# money_methods :tax_amount, :price
#
# Decorate a method, but with some additional options
# extend Spree::DisplayMoney
# money_methods tax_amount: { currency: "CAD", no_cents: true }, :price
# Use generated method with the same arguments as in wrapped method
# def tax_amount(order, country)
# display_tax_amount(order, country)
def money_methods(*args)
