# The web crawler we built at the end of Unit 3 has some serious
# flaws if we were going to use it in a real crawler. One
# problem is if we start with a good seed page, it might
# run for an extremely long time (even forever, since the
# number of URLS on the web is not actually finite). The final two
# questions of the homework ask you to explore two different ways
# to limit the pages that it can crawl.
