We've discovered and resolved the Null Pointer Exception. currently, if
you run CSCI201Maps main, it displays a tiny map within a JFrame.
TODO:
1) We've commented out all the other freeways except the 405 because
there's an error in drawing all the freeways. We need you to figure out
what's happening there.
2) Adjust the main so that we can simply add the UIMapPanel and the
SidePanel for simplicity.
3) Connect the JSONFileGetter/Parser (as a thread every 3 minutes) to do
the following:
	a) Adds cars to the FreewaySegments in GeoMapModel. Use the search
function inside of GeoMapModel to figure out which FreewaySegment we're
trying to access, then add the appropriate car. You need to add a member
variable and function within freeway Segment to add cars.
	b) Store data in the database based on the FreewaySegment you receive
from the search.
4) Freeway Segment average speed calcultor. Everytime you add or remove
a car, the freeway segment should recalculate it's own average speed and
update it into the database.
5) Draw Cars. This is mostly done, but just needs to be added to the map
and run as a thread.
6) Pass data into the Panels. Finish Set up GUI.
