    Assignment: Final Project
    NOTE: This project is used for maintaining quality control data on 
        incorrect orders placed for surgical pathology specimens. It will
        keep track of case number, ordering physician, ordering nurse, 
        the date entered into the system, and the nature of the error
        (e.g. incorrect history, wrong order type, etc).
        
        Variable user levels:
                1. highest level allows all database functions.
                2. middle level allows creation of new elements in all tables
                    except 'users.'
                3. lowest level only allows creation of new 'events.'
