[TIP] Custom execution of nose tests

[Alex Gaynor]

Sorry, I should have been more clear, I understand it's supposed to return a
callable, I just need to understand what exactly that callable is supposed
to do, essentially, is there an example of what the "default"
prepareTestCase does?  Also, returning None simply triggers the default
behavior, right?
