+# This test will ensure that a virtual C++ method from a base class can
+# be overridden in a derived class implemented in Python, and that when
+# the C++ method is called from C++ that the Python override is called.
+# In addition the Python override will pass the call on to the base class
+# implementation and this test will ensure that is successful as well.

+# The AddChild method is a good cantidate for this test because it is
