    The design document and information document are included under the doc
    directory now.
    
    Added a lot of documentation, particularly to the Schema class.
    
    Made a few changes to the ArithmeticOperator and BooleanOperator
    classes' simplify() methods so that we can do some basic
    simplifications.
    
    Added the StatisticsUpdater so that it's easier for students to modify
    statistics based on selection predicates.
    
    Fixed a bug in SelectClause where ORDER BY clauses were using the
    FROM-clause schema rather than the SELECT-clause schema.
