/*
	How to use (map) the Supermatter Auto-Setup feature:
	1. Have (map) a SM engine like normal.
	2. On top of every coolant injector (connector) ports add a `coolant_canister` marker.
	3. For every pump that needs to be maxed / turned on add a `pump_max` marker.
	4. For every connector port that needs an empty canister add a `empty_canister` marker.
	5. For every filter that needs to be set up for the coolant add a `filter` marker.
	   Note that the filters must be set up to filter the coolant back into the core loop by default.
	   Otherwise the auto setup will mess up and you'll end up without the correct coolant gas!
	6. For every freezer that needs to be on, add a `freezer` marker.
	7. For every SMES that needs to be online and maxed, add a `smes` marker.
	8. On top of the SM core map a `core` marker.
	9. Make sure to test that it actually works and doesn't blow up.
