//class Position:
//This class is a 3-vector that represents a position on the Earth's surface.
//
//   Methods:
//
// Lat()  : Returns latitude of this position.
//
// Lon()  : Returns longitude of this position.
//
// Distance(second position)  : Returns distance between this position and a second.  Takes
//                              a Position as input.
//
// SurfaceDistance(second position, surface elevation)  : Returns distance over the surface of
//              the Earth between the spot on the surface under/above this position and the spot
//              under/above a second position.
//              Input: a Position, and the distance from the center of the Earth to the surface at
//                     this Position.
