PlanetariaCollider least bounding sphere #130

It's worth mentioning that tangent spheres are the definition of the minimum, where applicable, even if they have a greater area.

The current bounding sphere calculation is bad at finding great circle boundaries.

An interesting concept is starting at "down" with respect to the PlanetariaArc and iteratively or algorithmically finding the tangent sphere's center.

Iterative versions would certainly work best with concave shapes.
