/**
 * A simple timer class that allows you to keep track of how much time
 * has passed between events.
 * 
 * You use this class by creating a timer as a member field in your actor (or whatever):
 * <pre>
 * 
 * private SimpleTimer timer = new SimpleTimer();
 * </pre>
 * 
 * Then when you want to start the timer (for example, when a shot is fired), you call the mark() method:
 * 
 * <pre>
 * 
 * timer.mark();
 * </pre>
 * 
 * Thereafter, you can use the millisElapsed() method to find out how long it's been since mark()
 * was called (in milliseconds, i.e. thousandths of a second).  So if you want to only allow the player to fire a shot every second, you
 * could write:
 * 
 * <pre>
 * 
 * if (timer.millisElapsed() > 1000 && Greenfoot.isKeyDown("space"))
 * {
 *     // Code here for firing a new shot
 *     timer.mark(); // Reset the timer
 * }
 * </pre>
 *

     * since this mark() call was made.
     * 
     * A second mark() call will reset the mark, and millisElapsed()
     * will start increasing from zero again.
