Comment(by ncohen):
Hello !
Yep, the number of threads is the number of paralell process that coin
uses to solve problem. It is really nice to have it use all the processors
available, but there *IS* to be some way to set it through this new class.
The other problem is the verbosity level. It does not appear in the
doctests because Coin is directly displaying information through stderr (I
guess), so Python does not mean anything. The problem is that if you type
: graphs.PetersenGraph().dominating_set() you will get some informations
from Coin you should not see unless you explicitely ask for them. I think
this is the only problem left with the package, considering we can also
solve this nasty compiling problem `:-/`
(The one I solve by adding "librt" to the flags, the one you solve by
removing it `:-p`)
