/*!
    \class QLandmarkCategoryFetchRequest
    \brief The QLandmarkCategoryFetchRequest class allows a client to asynchronously
    request a list of categories from a landmark manager.

    For a QLandmarkCategoryFetchRequest, the resultsAvailable() signal will be emitted
    as resultant categories are found (these are retrievable by calling categories()),
     as well as if an overall operation error occurred(which may be retrieved by calling
     QLandmarkAbstractRequest::error()).

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