1. Particle has a velocity at a time t
2. Forces act on the particle.  Compute change in velocity as result of
forces.
3. You now have new trajectory and new distance to be travelled in next
frame.
4. Do a trace to obstacles.
5. If vlength(Position-NearestObstaclePoint) < velocity*time,  then change
postion by velocity * time.
6. If it's greater, do a vdot at incident point, substract
(Position-NearestObstaclePoint) from velocity*time, go to step 4  until no
obstacles within distance.
