class DiscountType
attr_accessor :properties
# This is essentially copied from the payment class. There's an issue with how
# Rails auto-loads models, and finding out what classes have inherited from you.
#
# A subclass
# For example, a subclass called WonkaPayment can call payment_method :wonka
# Then callers can instantiate a WonkaPayment by calling Payment.create :wonka
#
# This will also define an instance method called "payment_method" on the subclass
# which will return a stringification of the symbol
