What is a reverse reference to the DOM object?
<p>In this link: <a href="http://css-tricks.com/snippets/jquery/jquery-plugin-template/" rel="nofollow">http://css-tricks.com/snippets/jquery/jquery-plugin-template/</a> it has a line of code that says</p>

<pre><code>// Add a reverse reference to the DOM object
base.$el.data("yourPluginName", base);
</code></pre>

<p>what does the "reverse reference to the DOM object" mean?</p>
