 * Demonstrates how behaviors can be added to generated industrial dialect objects.

 * <ul>
 * <li>Declare an interface with the additional methods that should be visible to callers.
 * <li>Declare an abstract class that implements the <em>generated interface</em> in order to have
 * access to the generated property / traversal methods.
 * <li>Add two dialect properties to the DDL declaration: {@code industrial:extends} with the name
 * of the abstract class and {@code industrial:implements} with the name of the interface.
