[computer-go] Caching of local search in NeuroGo?

I've used this with good results (i.e. minor loss of result quality but
big drop in number of nodes needed). It can be extended so 5 libs are
needed for tactical life on first few ply, then 4 libs for a few ply,
and after that 3 libs (3 libs is alive == ladder search).

I think I borrowed this idea from GnuGo, though it might have been
mentioned on this list before then.
