Commit message:

Extremely simplified the HelloWorld app now consisting in only GetLux and GetDistance synchronous functions calling. Removed the local 4 digit display and the red and the blue button management. The measure results are printed on serial over USB.

+/* This VL6180X Expansion board test application performs a range measurement and als measurement in polling mode
    on the onboard embedded top sensor. 
-   The board red slider select on the flight the measurement type as ALS or RANGE; the measured data is diplayed on the 
-   on bord 4digits display.
-
-   User Blue button allows to stop current measurement and the entire program releasing all the resources.
-   Reset button is used to restart the program. */

-/* Polling operating modes don`t require callback function that handles IRQ 
-   Callback IRQ functions are used only for measure that require interrupt */
-
-/* GetMeasurement is asynchronous! It returns NOT_READY if the measurement value 
-   is not ready to be read from the corresponding register. So you need to wait
-   for the result to be ready */
+   The result of both the measures are printed on the serial over.  
+   GetDistance and GetLux are synchronous!. So they blocks the caller until the result will be ready
