Detailed Description

Coordinates (lat, long) class definitions and functions library.

Coord class stores a double decimal degree latitude and double decimal degree longitude. It has a reach library for Marsden coordinates, distance, bearing and arithmetic calculations. This class has virtual methods for the sole purpose of CoordZ inheritance.
