public class MainMapAndOverviewMapMediator
extends javax.swing.event.MouseInputAdapter

This class mediates between the main map view and the overview map view. It does the following:
(1) Updates the rectangle on the overview map when the visible rectangle of the main map changes.
(2) Updates the main map visible rectangle when the user clicks on the overview map.
(3) Updates the main map visible rectangle when the user drags the rectangle on the overview map.
(4) Changes the mouse cursor to indicate that the rectangle on the overview map is draggable when the mouse moves into the rectangle.
