* initialize the center of rotation, versor, and translation of the
* VersorRigid3DTransform.
*
* This class derived from the CenteredTransformInitializer and uses it in
* a more constrained context. It always uses the Moments mode, and also
* takes advantage of the second order moments in order to initialize the
* Versor representing rotation.
