Comment:

 Hello Dima,

 As the end of december is coming fast, I started this review before the
 next beta. I added a commit at public/19632 that cleans a couple of
 things, and simplifies some code too. It would be really great if you
 could start thinking of what your computer does when you give it
 instructions, because a lot of computations was done for nothing.

 Two remarks:

 - For me the following doctest is too long, even for a "#long" doctest.
 Recently some guys were trying to figure out how to do something like
 "#long 2m" doctests for a better filtering.

 {{{
 sage: %time g=graphs.HaemersGraph(8); g
 CPU times: user 11.1 s, sys: 20 ms, total: 11.1 s
 Wall time: 11.1 s
 }}}

 - It seems that `partition` is not a partition of the vertex set but a
 partition of ... a partition of G into independent sets. Would it be
 possible to change the terminology a bit to avoid confusion?

 Thanks,

 Nathann
