Comments:

The SchmittC class registers N point sets using Schmitt's method.

There are M overlapping sets of points (Schmitt's notation), which means that each view has a point set, so M is the number of views. The overlap between two different views, are subsets of the point sets belonging to each view, and this is a correspondence set.

 Algorithm
   - Calculate all constant matrices (Abar, Pbar, all Q's =Qr+Qt).
   - Main Loop: While not converged do
        -> Calculate all N^j's & hence the quaternions (rotations).
        -> Calculate Bbar (diff between rotated centroids).
        -> Calculate Xbar (translations).
        -> Update Rigid Transforms.
        -> Calculate MSE.
        -> Determine if convergence has occurred.
 

The constructor allows guesses to be passed which will then be used to initialise the elements of rtsM. Each element being associated with a view.

The expected rigid transforms can be passed via the function SetExpectedRTs, which is only used for the calculation of delta theta.
