+/*
+ * README
+ * -----------
+ * 
+ * The AutoCloseDoor-script will monitor and after a (configurade) deley automatically clos eht door for you.
+ * It will only monitor doors within the same 'construct' (same "mechanical group", not Connectors)
+ * 
+ * Tag a door with [ACD] (including brackets) in its name to have the AutoCloseDoor-script watch it and automatically close if after 3 seconds.
+ * 
+ * You can also tag it with [ACD 10] to auto-close after 10 seconds (you can write whatever delay you want)
+ * 
+ * -----------
+ *
+ * This version has been slightly modified by Firq. All credit goes to the original author Ninlin (https://steamcommunity.com/sharedfiles/filedetails/?id=2371860127)
