	Aluminum is actually the most abundant metal in the Earth's crust,
	even more so than iron, but since it's a mid/late-game metal, the
	distribution in this mod is a little different. 
	
	Originally, I gave bauxite the same spawn patterns as iron, but this
	produced way too much bauxite in the same areas as iron, which led
	me to leave a ton of it behind until I could process it reliably.
	
	Also, I always felt it was weird to be climbing mountains and seeing
	nothing but rock and the occasional coal sticking out. I felt there 
	should be more ores at higher elevations, so bauxite is now found in
	those areas. Hopefully this will help alleviate the reduced findings
	at lower elevations.
