/* *****
 * The code below describes how to make a throbbing or automatic fade
 * sequence of messages.  It is important to note that this function is
 * NOT part of the Buffered Text-Fade Effect, but merely an example of
 * how it can be used.  In this example, the throb() function controls
 * the commands which are sent to the fade engine; it is called
 * repeatedly at set time intervals rather than using mouseover events
 * as triggers.
 *
 * Notes:
 * - A global array "hash" is used to keep track of where each
 *   animation is currently in the sequence.
 * - The list of messages defined in the fader *must* start at one (1)
 *   and count upwards without skipping any integers.
 * - The third line of the throb() function controls how fast
 *   commands get sent to the fade engine.  It waits only 100 milli-
 *   seconds when fading out, but 10000 milliseconds (10 seconds) when
 *   fading in; this means the message will remain visible for about 10
 *   seconds before fading out again.
 *
 * Other types of fade animation are possible simply by designing
 * different ways to control the fade-ins and fade-outs!
