 * \brief AcCurrent Click example
 * 
 * # Description
 * This application measures AC current through a conductor.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * SPI driver and click initialization.
 * 
 * ## Application Task  
 * Reads the value of AC current and displays it on the USB UART.
 * 
 * ## NOTE
 * An appropriate AC Current sensor needs to be connected to the click board.
