[cse491] grades for HW #7

[C. Titus Brown]

hi all,

I've graded HW #7, and added the grades into your svn repository under
hw7/GRADE.txt.  Please take a look and let me know if there's anything
that's confusing.

A few people asked for extensions, and I haven't graded a few of the test_apps
yet; if you don't have a numerical grade then that's why.  I'll get to those
on Monday.

cheers,
