class AssignmentFile
// This is a class of objects designed for the purpose of reading a text file
    // and converting it into a list of assignments, as well outputting a list
    // of assignments to a text file.  It is the interface between saved
    // assignment data (stored in a text file) and a list of assignments
    // that is being processed.  Each AssignmentFile has two corresponding
    // lists of assignments--one for uncompleted assignments and another for
    // completed assignments.  Use of this class requires the Assignment class
    // ("Assignment.h"), the AssignmentList class ("AssignmentList.h"), and the
    // StringTokenizer ("StringTokenizer.h") class written by
    // Dr. Mohammad Kuhail.
