Added new element, IPClassifier, which will be loved by all
example
c :: IPClassifier(tcp and dst host 10.0.0.20 and syn and not ack,
src 18.26.4.0/24 tcp www,
-)
This required changes to Classifier to improve its optimizations, which
means that Classifier may not be 100% correct, so if you are getting weird
behavior, remember that.
love,
ed
