*  Version 2.17.0.0", 2019-10-22
*
*  (c) CrossControl 2010-2019
*

 *  File description: 
 *  Light Sensor access. 
 *  The lightsensor suported by this implementation is a TAOS TSL2550 for 
 *  platforms other than VC.
 *  On the VC platform, the sensor is the Intersil ISL29035.
 * 
 *  Note that reading the light sensor using average calculation at the 
 *  same time as running the automatic backlight control is not supported.
 *  Also note that Lux values mentioned below (and in the Backlight class) 
 *  are not necessarily true lux values. The values received are lower than
 *  true lux values, due to the light guide in the front panel, where some 
 *  light is lost. It is still a measurement of the illuminance (in Lux).
 *
 *  Use the function GetLightsensor() to get a handle to pass on to the other functions. 
 *  Use the method Lightsensor_release(LIGHTSENSORHANDLE) to return the handle.
 *
 *  Example Usage:
 *  @include lightsensor_example.cpp
