Set Faculty.TBA.facultyNumber to 0.
Stub for SectionDaoTest & its dataset.
Made Schedule.TBA public.
Changed 'privateKey' to 'primaryKey'.
Implemented first dbUnit test -
SectionDaoTest.testGetByIdSubjectNoPrerequisites(). Implemented very
inefficient routine in SectionDao.getById() just to show process of make
things work before refactoring. Needs to be refactored to use one
SELECT/JOIN statement instead of 3 separate SQL statements.
Added contructor that takes instructor.
Entity.primaryKey defaults to zero.
Faculty constructor now public.
SectionDao.getById() now passes testGetByIdNoPrerequisites.
SectionDao.getById now handles SectionDaoTest.getByIdSubjectHas prereqs
but solution needs multiple SQL statements. Try to reduce to just one.
Also, solution doesn't yet support multiple nesting of prerequisites.
