In golois, I make golois compute many answers and verify that one of
is the one in the test.
I modified test 6 for gnugo.

not yet, results to come...

I have added this functionnality and corrected a bug due to
call to naive ladder in the new readconnect.c
I still have things which are missing but that are very clear in my

My current main problem is debugging readconnect for gnugo.
