// ShowTimenow:

    // To specify a timenow reference line on a Gantt chart
    //    1) Identify the date to use as the axis position for the timenow line.
    //       Generate the specified date as a SAS Date value.
    //    2) Optionally, create a StrokeLineStyle to define a line style for the timenow line
    //    3) Create a ReferenceLine with the defined line style and axis position
    //    4) Call the GraphModel's setTimeNowReferenceLineModel() to set the
    //       reference line as the graph's timenow line
