Look in the network graph, you're based on a very old commit.

https://github.com/uwcse440/web-cse440-au15/network

Get your master current:

git checkout master
git pull uwcse440 master
git push

Then rebase this onto that:

git checkout balance-feature-branch
git rebase master
git push -f

That'll update this pull request.

I cleaned up the history and merged this in #160.

The process I followed was the same as in #159, which I explained in #157.
