Arasan test suite

[jdart]

I have continued to enhance and expand my "Arasan" test suite and the latest version is available here:

http://www.arasanchess.org/arasan9.epd.

This now has 400 positions. Most are tactical although some require endgame knowledge. They range from easy to very difficult and generally the ones earlier in the file are easier than those later, although this is not always true. Arasan only get about 1/3 of the last 100 right.

Results from various versions of Arasan at 60 seconds/move can be seen here:
