++ \brief This class stores historical data values from a node.
++ \since 6.3
++
++ When a request to read history data is being handled, instances of this class
++ are used to store information about which node has been read, its values and
++ the status code.
++ The finished signal of a history read request will return a list of QOpcUaHistoryData
++ objects which can be parsed to review the results of the request.
