Issue 1:
Hey,

when running the most basic application, and using a component from material-ui@0.18.7

I get this error :

Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded

Node version:

7.9.0

npm version:

5.3.0

Windows 10
