 * \brief Thermo6 Click example
 * 
 * # Description
 * Demo application shows ambient temperature reading using Thermo 6 Click.
 * 
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * Setting the Click in the default configuration to start the measurement.
 * 
 * ## Application Task  
 *  It measures the temperature and logs a message about the current temperature.
