Use enzyme instead of ReactTestUtils for tests

I want to use [enzyme](https://github.com/airbnb/enzyme/blob/master/docs/guides/mocha.md) instead of the ReactTestUtils for unit tests in my project. As mentioned in this react-redux [issue](https://github.com/reactjs/redux/issues/1481), enzyme is pretty awesome and seems to be catching on.

I am having trouble configuring enzyme to work with the current karma and webpack set-up.

Is this something anyone is looking into? I couldn't find any issues relating to enzyme in this kit.
