/**
 * <p>Much like the GameOfLife example, this demo shows the basic usage
 * pattern for the 2D cellular automata implementation, this time however
 * utilizing cell aging and using a tone map to render its current state.
 * The CA simulation can be configured with birth and survival rules to
 * create all the complete set of rules with a 3x3 cell evaluation kernel.</p>
 *
 * <p><strong>Usage:</strong><ul>
 * <li>click + drag mouse to disturb the CA matrix</li>
 * <li>press 'r' to restart simulation</li>
 * </ul></p>
