 * \brief Servo Click example
 * 
 * # Description
 * This app shows how the servo motor can be controled by the Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device.
 * 
 * ## Application Task  
 * The servo motor at CH1 rotate in clockwise and counter clockwise directions.
