Add emergency video

Our first benchmarking video (which is also inserted into our technical report). The video presents a performance test of our framework with 15.000 agents on an emergency scenario.

The video is running in realtime on a single computer (iMac with 2,9 GHz Intel Core i5, 16 GB RAM and OSX El Captain 10.11.6).
