/**
 * <code>KeyInput</code> provides an interface for dealing with keyboard input.
 * There are public contstants for each key of the keyboard, which correspond
 * to the LWJGL key bindings. This may require conversion by other subclasses
 * for specific APIs. <br>
 * The status of spcific keys can be queried via the {@link #isKeyDown}
 * method. For each key that is pressed or released an event is generated which
 * can be received by a {@link KeyInputListener}, these are subsribed via
 * {@link #addListener(KeyInputListener)}. Handling of events is done inside the
 * {@link #update} method.
