					The singleton object of GUI_CONSTANTS encapsulates various constants
					such as colors, fonts, default image paths and size parameters.
					It also provides a 'ticks' function (not exactly a constant) which
					gives you the number of milliseconds since the app was started.
					
					This class is part of the XAE Extended Adventure Engine Project.
