To test the asymmetric rank humanSL profile on Windows

(Sorry for the long steps. This is just a debug feature.)

1. Download the all-in-one package (LizGoban-*_win_*.zip), unzip it, and double-click LizGoban *.exe.
2. From "Preset" menu, choose "Human-like Analysis".
3. From "Tool" menu, choose "Experimental" > "Enable debug menu".
4. From "Debug" menu, choose "Asymmetric humanSL rank" to toggle it on.
5. From "Edit" menu, choose "Preferences" to open the dialog and adjust the sliders as you like. Toggle "Lizzie style" off if the display is hard to see.

For example, you can set the blue slider to rank_1d and the red slider to rank_5k to compare the policies between "1d" and "1d against 5k". The former indicates "I'm 1d", while the latter indicates "I'm 1d and I know you're 5k". These policies, p and q, are shown by blue or red squares on the board (size = max(p,q), color = log(p/q)). Blue squares mean p > q, and red squares mean p < q.
