Good question. We have not checked this. But I don't see any point why
one can not implement a odeint-compatible stepper wrapping CVODE or
CVODES. Of course, there might be some subtle pitfalls with these
packages which make the wrapper very complicated or inefficient. It is
an interesting (and open) question.
