 Matcher structure can separate left&right links and know which way
 
+Now, to make things clear, the call sequence for RealBuoyViewManager
+is

+    sequence CallBuoyManager
+       call RealBuoyViewManager "render"
+           call BuoyViewMainNodeA "renderMain"

+               BuoyViewMainNodeA, BuoyViewNodeTypeB,
+                   BuoyViewMainNodeB.ghost);
+
+In the diagram, we first see RealBuoyViewManager render the view, calling
+BuoyViewMainNodeA to render the main node and getting a callback
+through the BuoyLinkListener interface about a link. This causes it to call
+BuoyViewNodeTypeB to render the buoy.
+
+Then, the mouse click comes which takes the focus to the buoy of type B.
+Its node type object is called to create the new focus object. Then, the 
+render pattern is repeated, but now with BuoyViewMainNodeB in the focus.
