Today I did some extra work on Freecell Solver. I'll report on "What's new on
the trunk" in a separate message, but just note that I've restored the
"sequences to false parent" Simple Simon move. It's not enabled by default and
needs to be enabled by using "-to abcdefghi" (the default test order for
Simple Simon is "-to abcdefgh").

After solving some bugs in my set-up, I reran the range analyser, and measured
the number of solvable/unsolvable games and the iteration numbers it took
Freecell Solver to report a verdict for them. Here are the final statistics:

As one can see, over 90% of the games are solvable, and most times the verdict
is reached after the first 100 iterations. This is a correction to:

Which is the previous Simple Simon statistics.
