[FRIAM] Great Circle

[Stephen Guerin]

In the early 90s, my expat friends in Beijing would often debate which were
the closer US Cities to Beijing by eyeballing the globe - wish we had this
too for easy lookup back then. Of course, we could have used lat/longs and
calculated haversine distances but we had pints to drink - and frankly it
would have been difficult for me to find the algorithm in the nascent web
back then ;-)
