% USAGE: [dist,phaseangle] = distance(lat,lon {,units} )
%
% DESCRIPTION:
% Calculate distance between two positions on glode using the "Plane
% Sailing" method. Also uses simple geometry to calculate the bearing of
% the path between position pairs.
%
% INPUT:
% lat = decimal degrees (+ve N, -ve S) [- 90.. +90]
% lon = decimal degrees (+ve E, -ve W) [-180..+180]
% units = optional string specifing units of distance
% 'nm' = nautical miles (default)
% 'km' = kilometres
%
% OUTPUT:
% dist = distance between positions in units
% phaseangle = angle of line between stations with x axis (East).
% Range of values are -180..+180. (E=0, N=90, S=-90)
