{Test 1: Open and read from Employee Database}

{  This is a simple use of IBX to access the employee database in console mode.
  The program opens the database, runs a query and writes the result to stdout.

  The test is run first with unidirectional buffering and then with bi-directional
  buffering.

  Both client side and server side filters are tested with bi-directional buffering.

  Finally, a beforeOpen handler is used to dynamically filter the results.
