Q = Quaternions.from_T(T, Q_guess);
This function returns a quaternions orientation Q. computed from a transformation matrix T and depending on the initial guess Q_guess. Generally, the transformation matrix T can be gained using a function from the TransformationMatrices package.
Description: Transformation matrix to transform vector from frame 1 to frame 2 (v2=T*v1)
Default Value: nullRotation()
Description: Guess value for Q (there are 2 solutions; the one close to Q_guess is used
Description: Quaternions orientation object to rotate frame 1 into frame 2 (Q and -Q have same transformation matrix)
