# has_counter_cache_on is a simple ActiveRecord extension
# which allows you to have multiple counters for a single
# association, counted when simple conditions are met
#
# The implementation is adapted from the current
# add_counter_cache_callbacks code in Rails.
#
# Example:
#
# class Submission < ActiveRecord::Base
