/**
 * Demonstrates the use of the <tt>Sampler</tt> classes.  The filter
 * architecture for this demo is as follows:
 * <pre>
 *     BallSampler (generates color data)
 *       |
 *     Tabulator (tabulates colors)
 *       |
 *       |____BarChart (charts distribution of colors for current sample)
 *       |
 *       |____Collector (collects the rel freqs of red over multiple samples)
 *              |
 *            NumericGrouper (groups the rel freqs)
 *              |
 *            Tabulator (tabulates rel freq groups)
 *              |
 *            BarChart (charts distribution of rel freq groups)
 * </pre>
 *
 * <b>BUGS:</b> If an "ungrouped" datum comes up (and this is possible),
 * then a <tt>NumberFormatException</tt> is thrown and the applet does not
 * work any longer.
