Provides Ajax support for controls, allowing them to handle and respond to Ajax requests. This is achieved through the {@link org.apache.click.ajax.AjaxBehavior} interface which extends {@link org.apache.click.Behavior} and adds the {@link org.apache.click.ajax.AjaxBehavior#onAction(org.apache.click.Control)} method for handling Ajax requests.

A default AjaxBehavior implementation is provided by the {@link org.apache.click.ajax.DefaultAjaxBehavior} class.
