 * In the State pattern, the container object has an internal state object that defines the current

 * <p>This can be a cleaner way for an object to change its behavior at runtime without resorting
 * to large monolithic conditional statements and thus improves maintainability.
 *
 * <p>In this example the {@link Mammoth} changes its behavior as time passes by.
