/**
* JXLoginPane is a specialized JPanel that implements a Login dialog with
* support for saving passwords supplied for future use in a secure
* manner. LoginService is invoked to perform authentication
* and optional PasswordStore can be provided to store the user
* login information.
*
* In order to perform the authentication, JXLoginPane
* calls the authenticate method of the LoginService
* . In order to perform the persistence of the password,
* JXLoginPane calls the put method of the
* PasswordStore object that is supplied. If
* the PasswordStore is null, then the password
* is not saved. Similarly, if a PasswordStore is
* supplied and the password is null, then the PasswordStore
* will be queried for the password using the get method.
*
* Example:
*
* final JXLoginPane panel = new JXLoginPane(new LoginService() {
* public boolean authenticate(String name, char[] password,
* String server) throws Exception {
* // perform authentication and return true on success.
* return false;
* }});
