+Uses the user-defined data in C<@data> to specify a database- for
+example, by passing in a DSN. The model class should open the database,
+and create a class for each table in the database. These classes will
+then be C<adopt>ed. It should also populate C<< $config->{tables} >> and
+C<< $config->{classes} >> with the names of the classes and tables
+respectively. The classes should be placed under the specified
+namespace. For instance, C<beer> should be mapped to the class
+C<BeerDB::Beer>.
