/** Base class for all Chart Accessibility objects except the root node (see AccessibleChartView)

    This class contains a reference to the ChartModel, thus, components can easily access all core functionality.

    Usage Instructions:

    <ul>
     <li>define the getAccessibleName() method of XAccessibleContext</li>
     <li>set the ChartModel using SetChartModel() for the first node before
         creating any children</li>
     <li>override UpdateChildren()</li>
    </ul>
