Space and Time Estimation

The trajectory estimation computes magnitude as a function of angle. We have also now computed angle as a function of time (frames * seconds/frame). Following the Gehrig paper, we use a 3rd degree polar polynomial for the upswing and a 5th degree one for the downswing. The angles used to compute f(t) are those of the inliers from the best trajectory fitting.

These results are a decent start, especially for the upswing.
