- method should add the new Course to the courses field, but cannot assign the Course if the instructor is already assigned to the Course

- cannot be assigned if total course students is over 500, use a boolean to return whether successful or not

- if successful, set the instructor field for the Course to that Instructor.

- getNumStudents() to return the nunber of students the instructor has
