Hi list, 
 
Let's say I have two points on an ellipsoid, with each point having a 
different height above the ellipsoid. I want to calculate a kind of 
"geodesic" between these points, where there's an assumption that the 
gradient of the height-above-ellipsoid for the "geodesic" is constant. 
 
Is this mathematically solvable? Or, more to the point, is it possible 
to calculate this using any of the methods exposed via geodesic.h?
