Line-Point Orientation Math Issue #1

Currently, the way I implemented fetch_correction in Bezier bezier.py does not properly calculate the offset proportions to get the line to start/end right at the edge of the circle:

The fix I came up with was to get the unit direction vector between the start and end points and then scale it to have length = radius of the start sphere. The resulting vector (d_rad_norm) contains the necessary offsets to add to the center to get the tracker line to start at the surface of the sphere in the direction of the end point.
