+/* End game for test Z, as bits work they are promoted up into the 
+   testcase above :)
+
+   TestN promoted the declare parents statements up
+   TestO promoted the fields up - a parent knows its children, a 
+         child knows its parents - but then used them incorrectly
+   TestP uses the fields correctly
+   TestQ ... tests some stumbling blocks I encountered before R...
+   TestR promoted getChildren() method
+   TestS promoted getParent() and setParent()
+   TestT ... tests some stumbling blocks I encountered before U...
+   TestU promoted addChild and removeChild
+   TestV removed the casts (wow!)
+   TestW promotes the pointcuts and few slight changes to the implementations
+     to bring it in line with whats in the AJDK
