This table is used for the auto-generated identifiers:

	<id name="id"><generator class="native"/></id>

and looks like this on MySQL:

+---------+---------+------+-----+---------+-------+
| Field   | Type    | Null | Key | Default | Extra |
+---------+---------+------+-----+---------+-------+
| next_hi | int(11) | YES  |     | NULL    |       |
+---------+---------+------+-----+---------+-------+
CREATE TABLE hibernate_unique_key (next_hi int(11));

If you set this property in your Hibernate config, then Hibernate will create 
this table automagically, as well as do all other necessary modifications to 
properly resemble your model:

	<property name="hibernate.hbm2ddl.auto">update</property>
