quat "Represent, store and transform a quaternion" "The mul messsage, with a quaternion argument, rotates the stored quaternion by the argument. bang outputs the stored value. reset sets it to zero rotation. quat takes an optional int argument - how often quaternions are normalized. Reduce to improve object efficiency, but increase to avoid floating point error creeping into the angles. Default every 30 operations."
