Expanding the simulation
Finally fixed the problem.  Turns out that it was not the communication between the applet and servlet, but a case of my own stupidity.  I had passed an arraylist of cars to the servlet, which then incased it in another arraylist for all of the results.  I sent that arraylist to the applet, and from there to the viewer.  The viewer thought that it was receiving an arraylist of cars, and so when it tried to access it to get the cars, it instead received an arraylist of cars, which I presume caused a runtime exception of some sort that Tomcat replied to by calling the method again.  A positive is that I've learned about logging though.
didn't include this earlier, but I had reworked it as well
AddCar button enabled, Simulation now 'runs', display works
