packageForLT06.FilledDotView
public class FilledDotView
The class encapsulates a view of a DotModel (where a "view" is a visual representation of data). This view is based on a widget container and can be instantiated and displayed.
The view is a single container widget that contains one widget, the DotDrawingPanel. This widget provides a single bounded two-dimensional plane. The dots in the data model are each drawn on the plane in their specified location and with their specified size. The user space is mapped directly to the device space.
Each dot is shown as a solid, filled shape.
The only constructor this class has is one that requires a DotModel object. It doesn't make sense to create this view without its data model.
This view is capable of listening to data models and will install itself on the passed data model. Any time the data model changes, this view will repaint itself.

public void changed()
Method that changes this view in response to any change in the data model. If the data model changes, the view repaints itself anew.
This method is invoked to signal to this listener that the model (upon which this listener has been installed) has been changed. This provides an opportunity for the listener to something in response to any change to the model.
Who invokes this method? Think of who has been given access to this view... The documentation for the constructor specifies that this view has been installed upon the specified data model. So the data model is able to invoke this method within its inner workings.
