/*

This applet demonstrates the following:
  * Creating buttons and catching the events
  * Creating and using TextFields
  * A bit of multi-threaded behavior (decrementing timer)
  * Using a timer (see timer code)

  -- (for CSE470 staff: This is what I (JB) added)
  * Using AWT's layout mechanisms. 
    (http://www.freejavahelp.com/tutorial/layouts/gridlayout.html,
    http://www.freejavahelp.com/tutorial/layouts/borderlayout.html)
  * Creating a custom dialog box with Frame.
  * Using checkboxes.
  * Using radio buttons.
  * Using choice boxes.
  * Using a Panel to sub-divide the space.
