    \brief The QPlaceRatings class holds rating information about a place.

    Rating information is used to describe how good a place is conceived to be.
    Typically this information is visualized as a number of stars.
    The average() function returns an aggregated ratings value out of a possible
    maximum as given by the maximum() function.
