Euler angles are not used in any Modeller interface; it's all rotation
matrices or rotation about an axis. The only place to my knowledge that
Euler angles are used at all in Modeller is internally for CG and QN
optimizations. For any exposed interface I agree that quaternions are
probably the best solution.
P.S. As regards putting this stuff in the IMP kernel, that wouldn't work
if you need to use any of the decorators, since those are defined in the
core module.
