route <what> <sectors>
    like map, but shows delivery routes for <what>, and doesn't show
    things you don't own. The delivery directions are shown as follows:

	^?^ - deliver to sector above this one
	 ?/ - deliver to sector up-right
	 ?> - deliver to sector to the right
	 ?\ - deliver to sector down-right
	v?v - deliver to sector below this one
	/?  - deliver to sector down-left
	<?  - deliver to sector to the left
	\?  - deliver to sector up-right
