title: How do I apply a Font Theme in React Material-UI?
body: <p>I'm trying to apply a google font to my Material-UI react project, but can't seem to get it to take.  I'm using mui 0.14.2.</p>
  
  <p>My <code>index.html</code> font load:
  <code>&lt;link href='https://fonts.googleapis.com/css?family=PT+Sans:400,700' rel='stylesheet' type='text/css'&gt;</code></p>
  
  <p>My component where I apply the theme:</p>
  
  <pre><code>import ThemeManager from 'material-ui/lib/styles/theme-manager';
  import LightRawTheme from 'material-ui/lib/styles/raw-themes/light-raw-theme';
  
  const App = React.createClass({
  
      childContextTypes: {
          muiTheme: React.PropTypes.object,
      },
      getChildContext: function() {
          return {
              muiTheme: ThemeManager.modifyRawThemeFontFamily(ThemeManager.getMuiTheme(LightRawTheme), 'PT Sans, sans-serif')
          }
      },
  
  ...etc etc
  
  }
  </code></pre>
