74

Hello @lilliealbert !  @hypatia and I worked on issue #74 today.  Does the light gray border in this commit work?

Also, I noticed that the schema changed after migrating and am wondering if that needs to be merged in as well.  I put that change in a separate commit, so it's easy to discard.  Let me know.
