//  Namespace:	DataVisualization.Charting
//
//	Classes:	CommonElements
//
//  Purpose:	CommonElements class provides references to common 
//              chart classes like DataManager, ChartTypeRegistry, 
//              ImageLoader and others. It is passed to different 
//              chart elements to simplify access to those common 
//              classes.
