[gnugo-devel] value_territory & simple Ko

I believe that this function should take into account Ko.  Rather than
count a point for a vertex with a dead stone, if that stone is in a ko,
only count it for 1/2 (or 1/3) pt.  

I'm not sure the best way to code this, but suspect it's easy.  Am
I on the right track?  See trevora:210, for example.


/* Give territorial value to each vertex.
 * A vertex with a lively stone has territorial value of 0.
 * For other vertices the value is
 * 1 if the vertex is classified as territory.
 * 0.35 if it is classified as moyo
 * 0.13 if it is classified as area
 * 0.0 if it is classified as neutral
 * One point is added for a vertex with a dead stone.
 * Furthermore black points have a negative sign.
 * The results are written to the territory_value[][] array of the
 * influence data.
static void
value_territory(struct influence_data *q)
