// ContainerFacade

// idioms:
//     
//     // specify multi segment
//     var ContainerFactory = MyApp.getContainerFactory();
//     var container = ContainerFactory.getContainer('SegmentA','SegmentB');
//     
//     // connect to all segment
//     container.connect();
//     
//     // at the first of your session
//     container.init();
//     
//     // method call for transaction object
//     // will propagete same method call in the facade.
//     var tx = container.getTransaction();
//     tx.begin();
//     tx.setAutoCommit();
//     tx.isolationLebelSerializable();
//     
//     # manage entity
//     instance.setFoo(bar);
//     
//     // same propagetion
//     tx.commit();
//     tx.rollback();
//     tx.close();
//     
//     // before you exit your session
//     container.drain();
//
