title: Add a component to all react-routes but one
body: <p>I want to apply a header to all pages but home. What would be the better approach to do this? I don't want to copy the header for every new page.</p>
  
  <pre><code>&lt;Switch&gt;
    &lt;Route path="/"&gt;
      &lt;Home /&gt;
    &lt;/Route&gt;
    &lt;Route path="/about"&gt;
      &lt;Header /&gt;
      &lt;About /&gt;
    &lt;/Route&gt;
    &lt;Route path="/users"&gt;
      &lt;Header /&gt;
      &lt;Users /&gt;
    &lt;/Route&gt;         
  &lt;/Switch&gt;
  </code></pre>
