Harness the power of infrared beaconing using VSMB2948SL and ATmega328P

/*!
 * @file 
 * @brief IrBeacon Click example
 * 
 * # Description
 * This library contains an API for the IrBeacon Click driver.
 * This application is suitable for high pulse current operation.
 * 
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Enables GPIO and PWM, sets the frequency and duty cycle and enables PWM.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of IR Beacon Click board.
 * It shows how to enable the device and gradualy increase the duty cycle.
 * Results are being sent to the Usart Terminal where you can track their changes.
