Sorted it out, I had forgotten to import one file. Sorry for the noise. Class patches nicely now; I am just having some test failures due to different orderings of some output sets. Is there a standard way of implementing tests that involve sets as outputs?
In a related matter, in the _set_ method, is it better to return a python set or a sage Set?
