title: How to use Material UI icons in React?
body: <p>I'm new to react and am working on an existing React component. I need to include an icon and noticed that some were already being brought in, like:</p>
  
  <pre><code>import KeyboardArrowLeftIcon from 'material-ui/svg-icons/action/keyboard-arrow-left';
  </code></pre>
  
  <p>I couldn't locate the folder (<code>material-ui/svg-icons/action/</code>), but tried to add a new icon:</p>
  
  <pre><code>import KeyboardArrowRightIcon from 'material-ui/svg-icons/action/keyboard-arrow-right';
  </code></pre>
  
  <p>However, this generates an error on compiling.</p>
  
  <p>Would anyone know how I could add a new icon? Or, why there is no apparent director for these icons?</p>
