Everything works (now doing the LKS DIMACS9 experiments).

- Fixed bug caused by incorrect use of NAMOA*. I was not setting the
  graph's in-edges but NAMOA*'s heuristics use them.
- NAMOA* experiments have no timouts. I have to manually check every
  once in a while if an experiment has been taking too much time and then
  manually kill it.
Put all calls to runQuery() inside forks with timeout.
