computes long/short path distance and heading
given the latitude and longitude (degrees and minutes).
You must input the lat/long of the two stations.
The output will then be relative from station1 to station2.
Input the two station lat/longs using the following format:
ddd.mmHddd.mmG, lead/lagging zeros can be left out.
d = Degrees, m = Minutes, H = Hemisphere (N or S),
G = Greenwich (W or E)
Units is 'n' for Nautical, 'k' for kilometers, and 's' for

gcb n 35.19N97.27W 38.51n77.02W (Moore to Washington D.C., mixed case)
gcb n 33.56n118.24w 55.45n37.35e (L.A. to Moscow)
