/**

 * Controls the main window which shows the currently selected person.

 * 

 * Unlike most applications, once the main window is closed a quit

 * is requested, and all the controllers are disposed, and the app should

 * exit organically.

 * 

 * Swing will automatically terminate the process if there are no more

 * windows open, no background threads running, and no more events left

 * to process in the event queue.
