Fix for Issue #80, "Click on nodes in the GUI is not accurate in some circumstances."  Code was incorrectly adjusting for the top left corner of the DefaultView as if the coordinates were absolute.  However, when the DefaultMouseManger does a lookup to see which element is at the mouse coordinate it uses the View/JPanel's relative mouse click coordinates.
