+// The following ifdef block is the standard way of creating macros which make exporting 
+// from a DLL simpler. All files within this DLL are compiled with the GXDLL_EXPORTS
+// symbol defined on the command line. this symbol should not be defined on any project
+// that uses this DLL. This way any other project whose source files include this file see 
+// GXDLL_API functions as being imported from a DLL, wheras this DLL sees symbols
+// defined with this macro as being exported.
