amoeba a new UCI engine

[supersharp77]

I am pleased to announce the release of amoeba 1.0, a new and original chess engine, available here: https://github.com/abulmo/amoeba
The main originality of this engine, is that it is written with the D language (http://dlang.org).
The way I build the evaluation function is also pretty original, with some very simple concepts and well tuned weights.

In CCRL 4040 scale, I hope my program to reach 2650 - 2700 elo. I also hope to increase its strength in future versions.

Enjoy it

Excellent engine...loads and plays well in Fritz gui..does not load and crashes in Lokasoft gui..(D language?)

The crashes under chesspartner are probably due to a bug in the compiler (gdc)
I upload a new version here, compiled with another compiler (ldc):
https://github.com/abulmo/amoeba/archive/1.2.zip
It works (on my laptop) with chesspartner 6, and the win32 version should be faster.
