/**
* \file
*
* \section Purpose
*
* Small set of functions for simple and portable LED usage.
*
* \section Usage
*
* -# Configure one or more LEDs using LED_Configure and
* LED_ConfigureAll.
* -# Set, clear and toggle LEDs using LED_Set, LED_Clear and
* LED_Toggle.
*
* LEDs are numbered starting from 0; the number of LEDs depend on the
* board being used. All the functions defined here will compile properly
* regardless of whether the LED is defined or not; they will simply
* return 0 when a LED which does not exist is given as an argument.
* Also, these functions take into account how each LED is connected on to
* board; thus, \ref LED_Set might change the level on the corresponding pin
* to 0 or 1, but it will always light the LED on; same thing for the other
* methods.
