 * \brief Gps Click example
 * 
 * # Description
 * This example reads and processes data from GPS clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and wake-up module.
 * 
 * ## Application Task  
 * Reads the received data and parses it.
 * 
 * ## Additional Function
 * - gps_process ( ) - The general process of collecting data the module sends.
