/*!
    \class QLandmarkImportRequest
    \brief The QLandmarkImportRequest class allows a client to asynchronously
    request that a landmark manager import a set of landmarks.

    For a QLandmarkImportRequest, the resultsAvailable() signal will be emitted
    when landmarks have been successfully imported by the manager.  The list
    of added landmarks may be retrieved by the landmarkIds() function.  The resultsAvailable()
    signal may also be emitted if an overall operational error occurs.

    Please see the class documentation for QLandmarkAbstractRequest for more information about
    the usage of request classes and ownership semantics.

    Note that for S60 and Symbian platforms, the waitForFinished() function is not
    supported for import requests and will always return false.
