title: How to use Outline icons in Vuetify app?
body: <pre><code>&lt;v-btn outline large fab color="indigo"&gt;
     &lt;v-icon&gt;edit&lt;/v-icon&gt;
  &lt;/v-btn&gt;
  </code></pre>
  
  <p>In <code>vuetify.js</code> docs, the example only have outlined icons using buttons. But my requirement is to get outlined icons without using buttons.</p>
