Docking Element for Static Cores

[Izon2887]

The idea is to add an element that provides the same docking mechanics that dynamic constructs have but for static constructs, mostly space cores though. 
 

It could operate like a detection zone, large bubble areas that a ship can come near and initiate docking to the construct without floating away due to gravity. It could also be used to deny someone from parking on the core and give the owners ability of ejecting a docked ship if they’ve been there too long. 
 

Have 3 different sizes for the element to have varying sized docking areas.
