+ * The pump looks up for the airlocks automatically based on airlock_pump_distance_limit and airlock_group_distance_limit values.
+ * When placed, the dir value (direction where the pipes are coming from) is considered as a direction towards the station (internal). The opposite direction is external.
+ * The airlock then tries to find airlocks or walls towards these directions until airlock_pump_distance_limit number of tiles reached.
+ * When it finds a valid object, then it tries to find airlocks, in directions perpendicular to the found tiles.
+ * And then adds them to the corresponding group (external/internal) until airlock_group_distance_limit number of tiles reached
+ *
+ * Example scheme of a valid configuration:
+ * A-----W
+ * A-----A
+ * W--P--A
+ * W-----W
+ * A-----W
+ *
+ * Where:
+ * A - airlocks
