 * \brief Ir Eclipse Click example
 * 
 * # Description
 * This is an example of IR ECLIPSE Click board
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of IR eclipse Click board.
 * When the beam from the transmitter is eclipsed by placing an object in
 * the gap ( like a piece of paper ), when the sensor is triggered, the 
 * counter is incremented by one. Results are being sent to the Usart 
 * Terminal where you can track their changes. Data logs on usb uart 
 * when the sensor is triggered.
