/** AuthDisplayMngr is a class that knows how to display various parts of
 * the authentication system.  It's currently used to generate the content
 * of the login screen and setup the password changing fields.
 *
 * Each Authenticator will have an object that is either an instace of, or
 * an instance of a child of AuthDisplayMngr.  URLHandlers can use this
 * objects of this class to setup displays that may be partially
 * Authenticator specific.  The purpose of putting all the information here
 * rather than in the actual Authenticator is that many Authenticators may
 * use the exact same display setup. And only the odd ones will be left
 * out.
 *
 * This class will show a display that is suitable for normal
 * password authentication.  To accomadate other types of authentication
 * this class can be inherited from.  When inherited form, each child class
 * should assure it's self access to any additional information that might
 * be needed.  This may mean including a pointer to the Authenticator which
 * is using that AuthDisplayMngr, or it may include access to other
 * classes.
