Implementation of the Seed Finder Algorithm based on a Hough Transform.
The intent of this algorithm is to take an input list of 3D space points and from those to find candidate track start points and directions. It does so by first performing a Principal Components Analysis of the input 3D hits and then projects them to the plane of largest spread. A standard Hough Transform method is then applied to attempt to identify straight line segments which can be used as seeds to the kalman filter tracker.
