 * \brief Angle2 Click example
 * 
 * # Description
 * This example showcases how to configure and use the Angle 2 click. This click senses
 * the magnetic field along the horizontal plane using an array of Hal effect sensors.
 * The module uses advanced Spinaxis technology based on a direct angle sampling app-
 * roach in order to provide reliable data quickly.                                         
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the click and logger modules. Additional con-
 * figuring is done in the default_cfg(...) function.
 * 
 * ## Application Task  
 * This function reads angle data from the click module and displays that data using the
 * UART console every 200 miliseconds.
