 * PHP class to convert Latitude & Longitude coordinates into UTM & Lambert Conic Conformal Northing/Easting coordinates.
 * 
 * This class encapsulates the methods for representing a geographic point on the earth in three different coordinate systema. Lat/Long, UTM and Lambert Conic Conformal.
 * 
 * Code for datum and UTM conversion was converted from C++ code written by Chuck Gantz (chuck.gantz@globalstar.com) from http://www.gpsy.com/gpsinfo/geotoutm/
 * This code was converted into PHP by Brenor Brophy (brenor@sbcglobal.net) and later refactored for PHP 5.3 by Hans Duedal (hd@onlinecity.dk).
