 * Test for the LiveUser class
 * ===============================
 *
 * This example sets up an authorization system using the LiveUser
 * class. You don't have to use this to use the LiveUser class(es), but
 * this way you don't need to take care of the login-process, storing
 * the user object in a session and more...
 *
 * This example is intended to be used with the auth XML driver.
 * No permission management is supported.
