# This script is a rough hack at the Apriori algorithm for IS 7036, Homework 1, Problem 1.
# The first section uses no validity checking or subsetting which effectively ignores Apriori
# but brute-forces an answer. Following that, there is a semi-validated section which confirms
# the results of the first approach.
