[ODE] dRFromEulerAngles interpretation

[Bill Sellers]

Either pick one of the standard versions or include all 24 (since  
some of us prefer a static frame to a rotating frame). There's some  
nice code by Ken Shoemake in Graphic Gems for converting back and  
forth between all 24 versions of Euler angles and quaternions.

However I've no idea what the licensing is like.

Cheers
