* Before adding traders

1. Make Cainan Economy and Stations
	-  Cainan Economy Completed
	-  Cainan Stations Completed
2. Make ITC Economy and Stations
	- ITC Economy Completed
	- ITC Stations Completed
3. Add Weapons to Weapons Forges so they can be bought by the player
	- done for Ageirans
	- done for Cainans
	- done for ITC
4. Introduce economy-exempt stations
	- done.
	- use the flag 'exempt=true' when defining them in STATIONS.txt
5. Make ships purchasable by the player
	- deferred while I think about some stuff

Then start adding trading AI
	THINK: Universe traders vs buy/sell best price????
		- give each station a buyer || seller for each ware they have?
