/**
 *  YColorLedCluster Class: RGB LED cluster control interface, available for instance in the
 * Yocto-Color-V2, the Yocto-MaxiBuzzer or the Yocto-MaxiKnob
 *
 * The YColorLedCluster class allows you to drive a
 * color LED cluster. Unlike the ColorLed class, the YColorLedCluster
 * 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.
