# <tt>ActiveRecord::Model</tt> can be included into a class to add Active Record persistence.
# This is an alternative to inheriting from <tt>ActiveRecord::Base</tt>. Example:
#
# class Post
# include ActiveRecord::Model
# end
#
module Model
# So we can recognise an AR class even while self.included is being
# executed. (At that time, klass < Model == false.)
