[ODE] swing and twist joint?

[Krystian Ligenza]

Hi,

I have question about joints. Did someone tried to implement swing and 
twist joint (or cone and twist)? Something like ConeTwistConstraint in 
Bullet? Using amotor to limit ball and socket joint dont work very 
efficient for me. Would be very hard to write it by my own (I have no 
experience in this area) ?

Thanks
