Ok, so I've added a mouse listener that, when you double click it, will
return the vehicle ID of whatever row you clicked on.  Right now it just
prints out that vehicle ID, but you can call whatever class you want
with that ID, or if necessary, I can have it return all of the car info
from that row. Whatever is necessary.
