    Added smoothOrder(0, ...) as Dymola 2023x assumes y to be smooth, and simulations can then fail if it differentiated this output.

    Changed icon to display dynamically which input signal is being outputted.
    This is for Buildings, issue 2033.

    First implementation, based on the implementation of the Modelica Standard Library.
