    \brief The QPlaceMatchRequest class is used to find places from one manager that match those from another.  It represents
    a set of request parameters.

    Places from another manager that may have corresponding/matching places in the current manager are assigned using setPlaces() or setResults().
    A set of further parameters are specified which determines the criteria for matching.

    The typical key for matching is the QPlaceMatchRequest::AlternativeId, the value is an alternative identifier attribute type of the format
    x_id_<provider name> for example x_id_here.  The provider name is name supplied to the QGeoServiceProvider instance.

    See \l {Matching places between managers} for an example on how to use a match request.
