    \brief The Ratings type holds place rating information.

    Rating information is used to describe how \e good a place is conceived to be.  Typically this
    information is visualized as a number of stars.  The \l average property gives an aggregated
    ratings value out of a possible maximum as given by the \l maximum property.
