Got rid of DAOException.  It was being used to hide the real cause of the problem (often a SQLException).  This made the code hard to debug.  It also did not provide any additional information on how to fix the problem.
* Fixed the import statements for Employee class.
* Got rid of EmployeeSearchCriteria class.  It was just the Employee class with a different name.
* Replaced EmployeeDAO's searchEmployees method with the simpler getEmployees method
* Got rid of DBUtil class
