UFO Alert Tool needs special math for Earth accuracy.

The following math is required to make UFO Alert Tool really accurate:
1. Ray-tracing a spheroid.
2. Great Ellipse distance between two points.
3. Shortest Distance from a point to a Great Ellipse.
These math problems are due to the Earth being flattened by gravity.
For now I will try to proceed with an spherical Earth but this will be less accurate.
The preferred math is with vectors so it can handle x,y,z positions returned by the ray-tracer.
This special math is needed for visualization of arcs across the Earth.
Bye for now,
Skybuck.
