Compile and link: 
    g++ DS18x20.cpp -L../ -lhubo -lpthread -lrt -o DS18x20.out
Run:
    ./DS18x20.out
Purpose:
    This demo shows how to list all 1wire devices, how to check whether a devixe is of the
    type of a DS18S20 or DS18B20 sensor and how to read the data from the sensor.
    It does not require further initialization.
