/**
 * This class represents a Phidget LED. All methods
 * to control a Phidget LED are implemented in this class.
 <p>
 The Phidget LED is a board that is meant for driving LEDs. Currently, the
 only available version drives 64 LEDs, but other versions may become available
 so this number is not absolute.
 <p>
 LEDs can be controlled individually, at brightness levels from 0-100.
 * See your device's User Guide for more specific API details, 
 * technical information, and revision details. The User Guide, along with other resources, can be found on 
 * the product page for your device.
