"""
The principal purpose of this view is to allow the automated testing of multiple clients
connected to the server at once, interacting in a way that is at least somewhat representative
of normal user behaviour.

As such, navigating to the loadtesting page on a client device will load an iframe which will
then use Javascript to automate user interaction with the site. It will try to watch videos and
do exercises in rapid succession in order to put strain on the server and associated network
connections.

So far the principal use for this has been testing with 30+ tablets connected over WiFi to a
server and seeing if the server and wireless connection can handle the strain.
