[arm-allstar] Shutting down a node safely in a vehicle, need some input

[Patrick Perdue]

If I could drive, and had a permanent node in my car, I'd probably rig 
something up to GPIO somehow, which would detect when the car has been 
turned off. This would then start a countdown timer, then shut off after 
the timer runs out, as you wouldn't necessarily want the node to 
shutdown as soon as you turn the car off. I've seen lots of 
installations like this for mobile radios that are wired directly to the 
battery. I'm not quite sure how this would work in that situation, though.
