Every time qsearch is called i count one node.

I could but i use a very difficult methode for which i'am not even sure that the
results are correct. Basically i first fill up a matrix where for every ray the
attackers are stored in attacking order. Then i cycle through this array to find
the least valued attacker and this proces is repeated until no attacker is left.
Then the score is calculated in a method like used in Crafty.

As i said, this is a very clumsy and time consuming matter. It simply takes to
much time to find these attackers.
