Using sensors to save energy consumed by gravity generators

Gravity generators are useful, but they consume energy. When do we usually need gravity on our ships turned on? Of course, when we are inside a gravity field, so we can walk. When we are outside, we don't need it. So why waste energy?The 2 core ideas are:1. Switch on a gravity field when you enter it. Switch it off on exit.2. Instead of one huge energy-wasting field have several smaller fields and have them turned on only when you need it.I made this example world to demonstrate the concept: http://steamcommunity.com/sharedfiles/filedetails/?id=434406543 Try walking from the red area to the green one and see how gravity generators turn on and off when and where you need them.Place sensors and adjust their detection areas according to their corresponding gravity fields. You can observe gravity and sensor boundaries when you have a working antenna on your ship, the generators/sensors are powered and turned on, and the "Show gravity range/Show sensor fields range" checkboxes are checked (press I and select the "Info" tab for that).
