/**

 * @author JK
 * As you know this is the CD Unit (SHIP) for your code in the harbor.
 * It is the only module that is specific to the Harbor Application server
 *  and it allows the application dropped into Harbor to run remotely.
 *
 * Just for the purposes of demonstration and to make one see just how much
 *  work harbor actually is... we have taken the original code from the application
 *  and we comment out what is not used and where Harbor specific API have been used
 * ie its a direct comparison to the standalone CD unit.
 * Approx 12 lines of code, to put a business application with its UI and dB pool online.
 * The application took 3 hours to make... its easy because debugging and testing
 * is easy in POJO. Its a stand-alone application so one cant even count that as Harbor
 * specific, but ok lets say we thought about the MVC (Coherent Disintegration) in
 * the app for an hour, also hard to count as Harbor specific because all it really does
 * is force good coding practice on the developer.
 * This took 5 mins.
 * Once you have done one, its fast, very fast, and the code is reusable anywhere.
