+ * This example is a modified version of PlainSQL that shows how to use Slick's plain SQL with regular classes,
+ * unfortunately the 22 property limit of case classes is not overcome.
+ *
+ * A simple example that uses plain SQL queries against an in-memory
+ * H2 database. The example data comes from Oracle's JDBC tutorial at
+ * http://download.oracle.com/javase/tutorial/jdbc/basics/tables.html.
