    \brief The QPlaceReply class manages an operation started by an instance of QPlaceManager and
           serves as a base class for more specialized replies.
 
    The QPlaceReply and each of its specialized subclasses manage the
    state and results of their corresponding operations.  The QPlaceReply itself is used
    for operations that have no results, that is, it only necessary to know if the operation
    succeeded or failed.
 
    The finished() signal can be used to monitor the progress of an operation.
    Once an operation is complete, the error() and errorString() methods provide information
    on whether the operation completed successfully.  If successful, the reply
    will contain the results for that operation, that is, each subclass will have appropriate
    functions to retrieve the results of an operation.
