# Permit the Frog
# ===============
#
# NOTE: The idea is to release it as a gem eventually, but for now, until we have
# used it in the real world for a while, let's just keep it here.
#
# Define permissions with something like this:
#
#     class Permit::Set
#       it.can :read, Product do |user, target|

# Public: generates a mixable singleton implementation dependent on a model key.
# Once you mix it into a model, your model gains an .instance method that will
# generate an object and cache it. Further calls to the .instance methods will
# return the same object.
#
# key - The name of the attribute we use to index instances. Defaults to "id".
#
# Example
#
#   # Called without arguments uses the "id" as key.
