Could Lizgoban divide ownshipSd into white osSd and black osSd? #71

Standard deviation are always bigger than zero. It looks like black player and white player are one player.

Ownership (black / white) is shown on the main board separately. Though I tried first to show both ownership and ownershipStdev on the same board, it was difficult to see for me.

Or, do you mean that ownershipStdev should be shown with different colors depending on the sign of ownership? This seems misleading. In the following picture, thick blue/red (= large ownershipStdev) on the subboard indicates "slightly black/white ownership" actually. Note that large ownershipStdev implies small |ownership| because V[X] = E[X^2] - E[X]^2 <= 1 - E[X]^2 (from |X| <= 1) in this case.

Well, it sounds right.
