 * \brief LedFlash2 Click example
 * 
 * # Description
 * This app demonstrate flash and torch mode on LED light.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device and sets the Click into "OFF" mode.
 * 
 * ## Application Task  
 * This function will demonstrate how to use the flash mode,
 * and the torch mode, with different power settings. 
 * It will then turn the Click off.
 * 
 * ## NOTE 
 * LED lights can be very bright, even on lowest power settings.
 * Avoid looking directly into the light when Click is in operation.
