relative rotations in the local (contact) coordinate system.
>>>
>> Last note: all the shear vectors are stored and updated with respect to
the global system, though the definition of a local system would be possible
(not done yet as we do not need it ATM). For the relative rotation I do not
see in ScGeom that we save it, we account for it once computing
relativeVelocity (either in precompute() or getIncidentVel() functions of
ScGeom). Have a look at https://www.yade-dem.org/sphinx/formulation.html to
see better the incremental algorithm if you are intersted in ScGeom.
