Center Avatar inside Toolbar with MaterialUI
<p>Is there any way to center Avatar component inside Toolbar with MaterialUI components?</p>

<pre><code>&lt;Toolbar&gt;
    &lt;ToolbarGroup float="right" lastChild&gt;
        &lt;ToolbarTitle text="Toolbar"/&gt;
        &lt;Avatar src="images/avatar.jpg"/&gt;
    &lt;/ToolbarGroup&gt;
&lt;/Toolbar&gt;
</code></pre>

<p>I have been playing with this few hours without any success.</p>
