Unable to use this with Require Js

Attempted using this nice component with Require Js using UMD way
### Issue - Since It tries to locate React and ReactDOM in globally(window object) and fails as requires doesn't do global exports.
```
var React = (typeof window !== "undefined" ? window['React'] : typeof global !== "undefined" ? global['React'] : null);
var ReactDOM = (typeof window !== "undefined" ? window['ReactDOM'] : typeof global !== "undefined" ? global['ReactDOM'] : null);
```
With my basic understanding, i managed to get it to work if above piece of code somehow checks `require('react') and require('react-dom')`.

Request suggestion to solve this.
