New chess engine: Clozza 1.0

Author: Colin Jenkins

Clozza - clozza.js is a simplified version of my Javascript chess engine Lozza.
clozza.c is a line-for-line hand-crafted translation of clozza.js into C, including a 2 x 32 bit hash.

The purchase process for the download version on the ChessBase website took only 5 minutes. Downloading the files from the cloud was even quicker. The installation itself, which involved five large files, took maybe 7 minutes, including restarting the system and entering the serial number I received upon purchase. The start image for Fritz 20 has a strange mosaic of colors; perhaps I'll get used to it.
