-- HIGH-LEVEL Internals
-- mesecon.is_power_on(pos) --> Returns true if pos emits power in any way
-- mesecon.is_power_off(pos) --> Returns true if pos does not emit power in any way
-- mesecon.turnon(pos, rulename) --> Returns true whatever there is at pos. Calls itself for connected nodes (if pos is a conductor) --> recursive, the rulename is the name of the input rule that caused calling turnon; Uses third parameter recdepth internally to determine how far away the current node is from the initial pos as it uses recursion
-- mesecon.turnoff(pos, rulename) --> Turns off whatever there is at pos. Calls itself for connected nodes (if pos is a conductor) --> recursive, the rulename is the name of the input rule that caused calling turnoff; Uses third parameter recdepth internally to determine how far away the current node is from the initial pos as it uses recursion

-- mesecon.rules_link(output, input, dug_outputrules) --> Returns true if outputposition + outputrules = inputposition and inputposition + inputrules = outputposition (if the two positions connect)
-- mesecon.rules_link_anydir(outp., inp., d_outpr.) --> Same as rules mesecon.rules_link but also returns true if output and input are swapped
-- mesecon.is_powered(pos) --> Returns true if pos is powered by a receptor or a conductor

-- RULES ROTATION helpsers
-- mesecon.is_power_on(pos) --> Returns true if pos emits power in any way
-- mesecon.is_power_off(pos) --> Returns true if pos does not emit power in any way
-- mesecon.turnon(pos, link) --> link is the input rule that caused calling turnon, turns on every connected node, iterative
-- mesecon.turnoff(pos, link) --> link is the input rule that caused calling turnoff, turns off every connected node, iterative
