    \brief The OPC UA Range type.

    This is the Qt OPC UA representation for the OPC UA Range type defined in OPC-UA part 8, 5.6.2.
    It consists of two double values which mark minimum and maximum of the range.
    Ranges are mostly used to store information about acceptable values for a node.
