static double distance	(	double	lat1,
		double	lon1,
		double	lat2,
		double	lon2,
		char	unit
	)			[static]

Calculate distance between two coordinates.

South latitudes are negative, east longitudes are positive.

Based on code from http://www.zipcodeworld.com/developers.htm

Parameters:

	lat1	Latitude of point 1 (in decimal degrees)
	lon1	Longitude of point 1 (in decimal degrees)
	lat2	Latitude of point 2 (in decimal degrees)
	lon2	Longitude of point 2 (in decimal degrees)
	unit	one of UNIT_STATUTE_MILES, UNIT_NAUTICAL_MILES or UNIT_KILOMETERS

Returns:

distance between the two coordinates
