[ODE] Setting Joint Positions

[Bill Sellers]

It might be nice to write some utility functions to do this since it  
is a bit of a chore (even for start positions rather than playback)  
if your data happen to be joint angles rather than absolute body  
positions. However you do have to be careful if you have closed  
chains since the chances are when you set the joint angles you are  
likely to end up with quite appreciable errors where the chain closes  
if you've done any rounding or the chain is long.

Cheers
Bill
