 * \brief Magneto Click example
 * 
 * # Description
 * MAGNETO Click carries contactless magnetic angle position sensor which delivers precise angle measurements down to 0.05º in 14-bit resolution.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * Magneto Click communicates with register via SPI by write and read from register and calculate float angle value. 
 * Results are being sent to the UART Terminal where you can track their changes. 
 * All data logs on USB UART for aproximetly every 2 sec.
