Thanks for trying it Geoff!

Latista does not allow the hash table size to be configured. That is probably
something that I should have considered. When the bitbases are loaded in memory
it uses 50 mb, and without them less. So I thought that is probably small
enought for most people.

If you have a tournament you want to enter it in and have a specific size, I
could do another point release in the near future, or send you a special
version.

Logging is also not configurable. You are right that it really should be though,
I will make sure it can be disabled in the next release.

About the bitbase dll. Daniel Shawul created a modified version of TSCP that
interfaces with the bitbase dll. It really did not take very much extra code to
get it working. (thanks again daniel). I simply saw what daniel did in TSCP and
did almost the same thing in Latista.

two things to be careful of when programming with the bitbases. 1) the dll
considers zero to be A1, and 63 to be H8. but the original tscp source used A8
for zero and H1 for 63. (like latista does).

also, I experienced some very odd behaviour when trying to load the dll if I had
multiple threads running. I discovered as long as i loaded it before latista
starts multiple threads it worked as expected.
