    Title: LED
 
    About: Purpose
        Small set of functions for simple and portable LED usage.
 
    About: Usage
        1 - Configure one or more LEDs using <LED_Configure> and
            <LED_ConfigureAll>.
        2 - Set, clear and toggle LEDs using <LED_Set>, <LED_Clear> and
            <LED_Toggle>.
        3 - Get the current status of a LED using <LED_Get>.
 
        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, <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.
