[Cgl] Limit for GomoryCuts

[Lou Hafer]

Thomas,

     You can read `if (!info.pass)' as `if (this is pass zero)', where 
pass is the number of cut generation passes at the current node.

     Can't speak to `limit >= 500'. There's a possibility it's archaic,
left from a time when problems were smaller.

                                                     Lou
