Swarming

• Quick Unity project to test out a described Swarming algorithm
• Testable in WebGL here: https://docjaq.github.io/Swarming/index.html
• Swarm spawning is random, so start is less than ideal
• Swarm robots pause if lead robot velocity is close to 0
• There are probably bugs in the UI/creation/deletion - added it right at the end for the WebGL build
• Note: actually slightly simplified in a few ways over what was discussed. Might benefit from some more work, and ability to parameterise different behaviours of the swarm/flock.
