Also, although it will give you no additional help on the programming 
side of things, the algorithm is also described in this paper on 
Geodesic Math:
http://www.salsburg.com/geod/geodesicmath.pdf

Specifically, the method being employed by this quiz is the "Class I, 
Method 1 or 'alternate'" method, described starting on page 9 and 
illustrated on page 10.

(Just in case my description confuses you, and you find something in 
this paper more clarifying.)
