\brief This class stores historical data values from a node.
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.
