 *   color LED cluster.
 * <para>
 *   Unlike the <c>ColorLed</c> class, the <c>YColorLedCluster</c>
 *   class allows to handle several LEDs at once. Color changes can be done using RGB
 *   coordinates as well as HSL coordinates.
 *   The module performs all conversions form RGB to HSL automatically. It is then
 *   self-evident to turn on a LED with a given hue and to progressively vary its
 *   saturation or lightness. If needed, you can find more information on the
 *   difference between RGB and HSL in the section following this one.
