title: React + Material UI, require is not defined
body: <p>I'm trying to use React with Material UI, but i still have the same error: require is not defined. I have this error on browser for TapEventPlugin, TouchEventPlugin, injectTapEventPlugin and ResponderEventPlugin.</p>
  
  <p>This is the code in my index.html: `
  </p>
  
  <pre><code>    &lt;div id="wrapper"&gt;
      &lt;/div&gt;
  
      &lt;script src="js/react.min.js"&gt;&lt;/script&gt;
      &lt;script src="js/JSXTransformer.js"&gt;&lt;/script&gt;
      &lt;script src="js/TapEventPlugin.js"&gt;&lt;/script&gt;
      &lt;script src="js/TouchEventUtils.js"&gt;&lt;/script&gt;
      &lt;script src="js/injectTapEventPlugin.js"&gt;&lt;/script&gt;
      &lt;script src="js/ResponderEventPlugin.js"&gt;&lt;/script&gt;
      &lt;script type="text/jsx" src="js/index.js"&gt;&lt;/script&gt;
  &lt;/body&gt;`
  </code></pre>
  
  <p>And this is my js file: </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>var React = require('react/addons');
  var injectTapEventPlugin = require('react-tap-event-plugin');
  injectTapEventPlugin();
  var mui = require('material-ui');
  var ThemeManager = new mui.Styles.ThemeManager();
  var AppBar = mui.AppBar;
  
  var ApplicationBar = React.createClass({
              render: function(){
                  return &lt;AppBar title='Title' iconClassNameRight="muidocs-icon-navigation-expand-more"/&gt;;
              }
          });
  
  React.render(
      &lt;ApplicationBar /&gt;,
      document.getElementById('wrapper')
    );</code></pre>
  </div>
  </div>
  </p>
  
  <p>Any idea?</p>
