Francois Belair 85784791ec Add and have most demos use specialized agents
The agents auto-update themselves and can calculate their velocities.
This keeps the user from having to create an update_agent function.
It can also save the user from having to keep track of and update
velocities at all by using the provided `apply_steering` method.

Closes #15, closes #16
