When you print out a collection of arbitrary objects, Python shows you
the *repr* ("representation") of each one. The default repr for a
custom class just shows the class name and the object's unique ID,
which isn't terribly useful. Create your own custom representation by
adding a method to your cvor class:

def __repr__(self):
    return "some nice descriptive string"

It's up to you to decide how to build that string, but that's what
will be shown.

Incidentally, you may want to consider the namedtuple type; it might
be more what you want.
