Class SphericalFibonacciPointSet

A Spherical Fibonacci Point Set is a set of points that are roughly evenly distributed on a sphere. Basically the points lie on a spiral, see pdf below. The i-th SF point of an N-point set can be calculated directly. For a given (normalized) point P, finding the nearest SF point (ie mapping back to i) can be done in constant time.
