title: Access Fluid extbase variables globally in another extension
body: <p>I have a view assigned and used for breadcrumbs in one extension</p>
  
  <pre><code>    $this-&gt;view-&gt;assign('breadcrumbs', $breadcrumbs);
  </code></pre>
  
  <p>I'd like to access and use this variable outside the scope of the extension, so in another extension. </p>
  
  <p>However I cannot find the variable when I do a extbase variable dump from the latter extension. Can I somehow make this variable accessable globally for the installation?</p>
  
  <p>Is there some typoscript setup I am missing? Something equal to partialRootPaths for variable? </p>
