 * Java programming assignment 3.
 *
 * Last week I was still throwing around the idea of having each on-screen object
 * running in a seperate thread.  However, java's thread mechanism isn't really up
 * to this.  (I don't know that any thread mechanism is...)  So we've abandoned
 * that idea.
 *
 * This week I've mainly been working on the general layout of our program.
 *
 * We've worked out that we will employ around 6 threads:
 *
 * * Event handling
 * * Local player's Dudes.  (Movement and probably learning.)
 * * Remote player's Dudes.  (Movement and probably learning.)
 * * Temples.  (Animation, mainly.)
 * * Network daemon.  (send out the local movements.  Maybe recieve the incomming.)
 * * Reproduction.  (I haven't decided yet, but this may be handled by its own thread.)
 *
 * On the data structure side of things:
 *
 * * Linked list of local user's Dudes.
 * * Linked list of remote user's Dudes.
 * * Linked list of temples.
 *
 * These three lists are each animated by one of the threads layed out above.
 *
 * * 1024 x 768 2D array of integers.  We may use something like this to
 *   keep track of where people are.  This will help with figuring out which Dude
 *   was clicked on, and also help prevent a moving Dude from running right over
 *   another non-moving Dude.
 *
 ********************************************************************************
 *
 * Below is the second version of my DudeList class.  Two instances of this class
 * handle the local user's and the remote user's Dudes.
 *
 * I have yet to completely figure out how to cordinate access to these lists.  Both
 * the update (movement) processes, the event handling process and perhapse the
 * reproduction process have to be able to access them.  Currently I'm thinking that
 * I can suspend the update process, update the list, and then resume the process.
 * However I am still working on getting it to work correctly.  (Attached you will
 * find my current trial code.  Depending on one's timing the code works fine.  There
 * is a race conditon somewhere that I have yet to find.
 *
 * This code can be found on my web page.  I will also set up a runnable binary.
