Remove Python swigrun example

Browse source 
By default it doesn't work as it does not call the CEO's __del__ method
as indicated in the comments. __del__ is called with -builtin but
then the base class's __del__ is not available and so it errors out.
Python 3 and -builtin goes into an endless loop. So removing as
hopelessly broken.
