/**
* Returns all the beans associated with $bean.
* This method will return an array containing all the beans that have
* been associated once with the associate() function and are still
* associated with the bean specified. The type parameter indicates the
* type of beans you are looking for. You can also pass some extra SQL and
* values for that SQL to filter your results after fetching the
* related beans.
*
* Don't try to make use of subqueries, a subquery using IN() seems to
* be slower than two queries!
*
* Since 3.2, you can now also pass an array of beans instead just one
* bean as the first parameter.
*
* @param RedBean_OODBBean|array $bean the bean you have
* @param string $type the type of beans you want
* @param string $sql SQL snippet for extra filtering
* @param array $bindings values to be inserted in SQL slots
* @param boolean $glue whether the SQL should be prefixed with WHERE
*
* @return array
