Interactive U.S. Travel Planner

Combine assignments 1, 2, and 3 into a single user-friendly
application.

It should

 + Allow the user to select two towns or named places in the U.S.
   by typing their names and states

 + Find the data for those two locations in the Alphaplaces file

 + Select and display the topographical data file that covers
   both locations and mark them on the map

 + Using the closests.txt datafile, find the highway intersections
   that are closest to the two selected locations

 + Find the shortest route between the two selected locations.
   Display this shortest route both as visible lines following
   the roads on the map display, and as text output giving
   instructions on which roads to take.

As a reminder, all the necessary data files and their descriptions
can be found here: http://rabbit.eng.miami.edu/geographical/

Combine your program code with sample runs (screenshots) in a
single readble (that means choose sensible fonts for the code
and make sure your lines aren't too long to fit on the page
when printed) document, either word or pdf, and make sure your
name is on the front.
