 * \brief Magneto7 Click example
 * 
 * # Description
 * This demo application reads position of a magnet above the sensor.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device.
 * 
 * ## Application Task  
 * Waits for INT pin to go LOW, gets raw data, converts it to uT and logs results.
