Comment (by vbraun):
Is `G.copy` implementing deep copy or shallow copy? The answer is clearly
"neither" (or, more precisely, deep copy plus a grab bag of stuff that is
not copy). So it should be labeled more accurately. Then people that
subclass !GenericGraph wouldn't be so confused by it, this ticket is plain
evidence that it is confusing. I overrode `__copy__` which now means that
the grab bag of non-copy stuff is gone from Sandpile. I say good riddance.
But it does make it inconsistent with what is going on in the base class.
