FunkRCA demo

This is a demo of velocity based avoidance. It is based/inspired by the theory behind RVO2 and ORCA.

• 3D implementation (2D in the works). 
• Agents use Ackerman steering.
• Implements both moveable and stationary obstacle avoidance.
• There are 4 demos: 1) Fish avoiding a wall, 2) Fish being congested travelling through narrow openings, 3) Flyer vs missiles, 4) Flyers vs flyers in formation. 
• Demos have have attributes that can be varied to explore more about velocity based avoidance.
