```
public class StalemateTester
extends Object
```
Tools for testing a rule set for a possibility of a stalemate. A stalemate is achieved when no piece cannot be removed from the board any more. This class may be useful for a rule set designer, to ensure that any rule sets offered to players will never stalemate. This tool was designed for GS4, and is not meant to work with the GS5 rule syntax.

    Parameters:
    
    pieceGroups - The m-board whose content we'll try to remove. The method modififes the content of the board, removing all pieces it can.
