// BasicRequirements:

// Basic requirements for creating a Gantt chart:
//   1) Create a data source, usually a Java TableModel
//   2) Create a data model that uses the data source
//   3) Assign the Task variable role and the Start and
//      Finish roles for dates you are tracking
//   4) Construct a GanttChart that uses the data model. You
//      can use the constructor to apply the of the STYLE_GANTTCHART
//      graph style to the chart. STYLE_GANTTCHART was specifically
//      designed for Gantt charts.
// To set a title or footnote, get the appropriate GanttChart
// title or footnote, and then set the returned object's text
