title: Fabric.js: Get objects by name
body: <p>Is it possible to get <code>Fabric.js</code> objects by name? I can add subclass which will allow me to add custom name property to objects. But after that can I call objects by name instead of index? e.g</p>
  
  <p>calling by index <code>canvas.getItem(0);</code></p>
  
  <p>I want something like <code>canvas.getItemByName(itemName);</code></p>
