Set the number of cells to use in one direction.
<p>
Total cells will be 'number*number'. A cell is a logical unit that can keep a number of generated positions. Using bigger (fewer) cells means that more positions are generated at once (possibly causing hickups when this happens). Smaller cells may mean more runtime overhead. Default is 50.
