So do we add a rollout option as the analysis level (and another tab to the move
filters maybe)? I'm not too familiar with this area.

As to the actual implementation I think we just treat the mini-rollout in the
same way as the other plys for rollouts and game analysis, so it's done on one
thread. There isn't so much global data to make the rollouts independent. As
for evaluations/gnu playing then this would need splitting out to utilise
multiple threads.

It doesn't sound too tricky in theory...
