The analyzer is now found in analyzer.py and uses the '-f' flag for
GZIPed input files. Bundled with the previous PR commit, this update
should now be clearer.
Previously, the analyzer assumed that two consecutive flows would be a
pair. This proved unreliable, therefore a new comparison algorithm is
ussed. It utilizes the IP addresses and the 'first_switched' parameter
to identify two flows of the same connection.
More improvements can be done, especially filtering and in the
identification of the initiating peer.
Tests still fail, have to be adapted to the new dicts and gzip.
Uses the analyzer's new stdin-reading capabilities to test the analysis
without having to write temporary files. Also removes most of the delays
because the listener can keep up now.
