Merge pull request #42 from austenlauria/master

Edited pcap_test.py to accomodate unit tests, added test_pcap.py to perform unit tests on pcap. Also packets are now happily sent to front end in a json object. Tests fail on Travis, but pass on my laptop. I'm guessing it won't wait to actually capture packets, or something.
