  116. 	 * The DataGrid class is a list-based component that provides a grid of
	 * rows and columns. You can specify an optional header row at the top 
	 * of the component that shows all the property names. Each row consists 
	 * of one or more columns, each of which represents a property that belongs
	 * to the specified data object. The DataGrid component is used to view data; 
	 * it is not intended to be used as a layout tool like an HTML table.
	 *
	 * <p>A DataGrid component is well suited for the display of objects that contain
	 * multiple properties. The data that a DataGrid component displays can
	 * be contained in a DataProvider object or as an array of objects. The columns of a DataGrid
	 * component can be represented by a list of DataGridColumn objects, 
	 * each of which contains information that is specific to the column.</p>
	 *
	 * <p>The DataGrid component provides the following features:</p>
     * <ul>
	 *     <li>Columns of different widths or identical fixed widths</li>
	 * 	   <li>Columns that the user can resize at run time</li>
	 * 	   <li>Columns that the user can reorder at run time by using ActionScript</li>
	 * 	   <li>Optional customizable column headers</li>
	 * 	   <li>Support for custom item renderers to display data other than text
	 *         in any column</li>
	 *     <li>Support for sorting data by clicking on the column that contains it</li>
     * </ul>
	 *
	 * <p>The DataGrid component is composed of subcomponents including ScrollBar,
	 * HeaderRenderer, CellRenderer, DataGridCellEditor, and ColumnDivider components, all of which 
	 * can be skinned during authoring or at run time.</p>
	 *
	 * <p>The DataGrid component uses the following classes that can be found in the dataGridClasses package:</p>
     * <ul>
	 *     <li>DataGridColumn: Describes a column in a DataGrid component. Contains the indexes, 
	 *         widths, and other properties of the column. Does not contain cell data.</li>
	 *     <li>HeaderRenderer: Displays the column header for the current DataGrid column. Contains
	 *         the label and other properties of the column header.</li>
	 *     <li>DataGridCellEditor: Manages the editing of the data for each cell.</li>
     * </ul>
