Control error in the 3D Rotation coordinate map.
Computes the error in the angle rotated by the system using a slightly modified version of Eq. (41) from [143]. The equation is
\[ \delta\vec{q} = \frac{\vec{C}\times\vec{X}}{\vec{C}\cdot\vec{X}} \]
where \(\vec{X} = \vec{x}_A  \vec{x}_B\) and \(\vec{C} = \vec{c}_A  \vec{c}_B\). Here, object A is located on the positive xaxis and object B is located on the negative xaxis, \(\vec{X}\) is the difference in positions of the centers of the mapped objects, and \(\vec{C}\) is the difference of the centers of the excision spheres, all in the grid frame.
