WIP Better Elevators

this is a WIP I need help with it.
I am posting it for demonstration reasons only.

my goal is to make a elevators more like the ones in real life

implemented features
--made elevators have two inputs(pulse). one for top, one for bottom.
--made elevators have two outputs. one for top, one for bottom.
--made elevators have waiting period before they can be called again.

planned features
--make platforms solid so people can't get stuck in elevator shafts.
--make long elevators have a middle floor.
--make elevators able to store calls, so people don't have to spam the button .

current bugs
--relaunching starbound and loading the world causes elevators to error. placing them down again fixes it.
--when reloading the platforms snap back to their starting positions
