    \brief The Location element holds location data.

    Location elements represent a geographic "location", in a human sense. This
    consists of a specific Coordinate, as well as an Address and a
    BoundingBox. The BoundingBox delineates the limits of what geographic area
    is considered "part of" the location. For example, a Location representing
    a house would have the Coordinate set to the center of the house's block
    of land, the Address to its street address, and the BoundingBox would show
    roughly the limits of the block itself.

    The Location element is most commonly seen as the contents of a search
    model such as the GeocodeModel. When a GeocodeModel returns the list of
    locations found for a given query, it represents these as Location elements.

    \section2 Example Usage

    The following example shows a simple Location element being declared with
    a set \l{coordinate} and \l{address}.

    \code
    Address {
        id: houseAddress
        ...
    }

    Coordinate {
        id: coord
        latitude: -27.3; longitude: 153.1
    }

    Location {
        coordinate: coord
        address: houseAddress
    }
    \endcode
