Comment (by ncohen):

 > Exactly, whatever the method, at some point we need a certificate. So
 either I ensure that __hyperbolicity__ always returns a solution, or I
 have to test the result afterward, or both.

 And I take it that you do not like the certificate
 `[g.vertex_iterator().next()]*4` for hyperbolicity 0 ? It looks like it
 would reduce the amount of code ...
