Homework Assignment 7 Grading:

The file H7handinReport.txt contains the logins of students who turned
in their work electronically (in addition to info about extra or misnamed
files).  The rest of the students submitted paper solutions (or nothing).

Comments to add to student's gradesheet (as an overall comment):
  Good job!
  No work submitted.

Note: for each question or question part that a student gets completely correct,
make sure to add the comment:
  Good job!
so the student's gradefile contains some feedback for that question/question part
