Made api more Ruby-like and fixed some bugs.

These are some changes that I made a while back. I thought the api was maintained by shopstyle, so I submitted the PR to the wrong fork. Here it is again.
But they've forked it and rebranded it as an official PopSugar library. Even built a demo app on top of it. This coupled with the fact that you haven't received funding, or even acknowledgement for your work, makes me think that something ain't right.
