ostrat.pchess

This is a package for Chess and Draughts (also known as Checkers). It has been included in the main Strat library, as useful to have code. Because they are finished games, with established rules and iconography. As opposed to applications like GOne, GTwo etc, which are super simple games merely created for the teaching of the use use of the ostrat libraries. And also as opposed to the games in the Dev module which are intended to be developed into interesting games which may at some point have their own individual repositories.
