OneAxisEllipsoid.projectToGround(...) fails at poles
When evaluated for a point on the minor axis of the ellipse projectToGround(Vector3D, ...)
returns NaN while projectToGround(TimeStampedPVCoordinates, ...)
throw a NPE. transform(PVCoordinates, ...)
is also affected since it calls projectToGround(...)
The problem appears to be a divide by zero when trying to determine the meridian. The attached diff for the test cases shows the problem.
