 * Meta
 *
 * Beans can have meta data. Meta data will not be stored
 * in the database and cannot be loaded from the database
 * (except for using special meta masks - this feature is available
 * in 4.3.2+). This test suite tests whether we can set and get
 * meta data from beans and verifies meta data does not end up
 * in the database.
 *
 * @file    RedUNIT/Blackhole/Meta.php
