Thats right.

Indeed, it will make 3 useless quaternions. Mmmh.. in fact it could be
moved to base ScGeom. relSpin would be dragged by pure 3D interactions
but it's only one vector.
In that case CFLaw could work with two different geometries (ScGeom for
incremental, ScGeom6D for total).
Let's see it work first, then we can think about design.

Cheers.
