This page was created to help debug and study webrtc issues such as
bandwidth estimation problems. It allows one to easily launch a test
case that establishs a connection between 2 peer connections

<!-- In order to plot graphs, this tools uses google visualization API which is
loaded via goog.load provided by google api. -->
<script src="//www.google.com/jsapi"></script>
<!-- This file is included to allow loopback_test.js instantiate a
RTCPeerConnection on a browser and version agnostic way. -->
<script src="adapter.js"></script>
<!-- Provides class StatTracker used by loopback_test.js to keep track of
RTCPeerConnection stats -->
<script src="stat_tracker.js"></script>
<!-- Provides LoopbackTest class which has the core logic for the test itself.
Such as: create 2 peer connections, establish a call, filter turn
candidates, constraint video bitrate etc.
