 * Storage driver for using multiple storage drivers in a fall through fashion

 * This storage driver provides a mechanism for working through multiple

 *
 * array(
 *   array(
 *     'type'    => <standard container type name>,
 *     'options' => <normal array of options for container>,
 *   ),
 * );

 * Full example:
 *
 * $options = array(
 *   array(
 *     'type'    => 'DB',
 *     'options' => array(
 *       'dsn' => "mysql://user:password@localhost/database",
 *     ),
 *   ),
 *   array(
 *     'type'    => 'Array',
 *     'options' => array(
 *       'cryptType' => 'md5',
 *       'users'     => array(
 *         'admin' => md5('password'),
