[ODE] RE: Ragdoll sample with multiple solvers

[Mike Reinstein]

That ragdoll physics demo is funny...I keep picturing it being used in an 
insurance company commercial with a guy doing the voice over as dozens of 
stick figures fall down the stairs "Here at fidelty mutual, we understand 
that accidents DO HAPPEN...."
