 * \brief Lem Click example
 * 
 * # Description
 * Demo app measures and displays current by using LEM Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes SPI, LOG and Click drivers.
 * 
 * ## Application Task  
 * This is an example that shows the capabilities of the LEM Click by measuring 
 * current passing through the conductor placed through the hole on the sensor.
