/**
 * @author tims
 * 
 *         This is a simple implementation of the Bootstrap
 *         dismissible alert with two buttons.
 * 
 *         The content, and the button text are in models. There are
 *         two abstract methods for the button callbacks. The alert
 *         will be hidden when either of the buttons are clicked.
 * 
 *         The X at the top right of the alert will only hide the text
 *         and not call back to the java.
 * 
 * @see Bootstrap
