* STILL TO DO
*
- * 1. Change other constants - such as Num Countries etc.
- * Just requires variables to be assigned, then dynamic allocation in
- * a few places. Some checks needed in the server to check the world
- * hasn't changed size etc.
- * 2. Could look at loading in planes, units etc. Should be easy enough.
