Examples of civquest.util.Coordinate

civquest.util.Coordinate
This class represents one coordinate (x,y) in 2d-space. It uses int-values and supplies functions for comparing coordinates and for performing some basic calculations (like adding another coordinate) on them. The coordinate-values are saved in x,y. These fields are public for convenience (and because you can't do anything wrong with these values). Note that all calculation-functions return NEW Coordinate-objects.
