 * \brief Color9 Click example
 * 
 * # Description
 * This application collects data from the sensor and logs green, blue and red 
 * measurement readings.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialize the driver and test if the sensor is
 * present. If the ID read from the sensor is correct
 * execute the initialization procedure.
 * 
 * ## Application Task  
 * Wait for the color data to be available then read the data
 * and send it to the serial port.
