// ShowBreaktime:

    // To show break times in a chart, the break dates must be defined in a data
    // file that is used as the source for a GanttChartBreakTimeTableDataModel.
    // The break dates are associated with all schedule tasks, unless a Calendar
    // variable is set in both the break data and the schedule data to assign the
    // breaks to a calendar string.
