title: Dot notation to arrays
body: <p>I got a string <code>'tileBlock.tag.title'</code> and an Hash like this:</p>
  
  <pre><code>{
    "title"=&gt;"headline",
    "body"=&gt;"body text",
    "link"=&gt;"#",
    "tileBlock"=&gt;{"title"=&gt;"Home", "tag"=&gt;{"title"=&gt;"home", "id"=&gt;45}, "active"=&gt;true}
  }
  </code></pre>
  
  <p>Is there a way to transform <code>'tileBlock.tag.title'</code> to something like <code>'object[:tileBlock][:tag][:title]</code>?</p>
