<li><b>scope</b> : Object<p class="sub-desc">The scope in which to execute the handler function. The handler function's "this" context.</p></li>
<li><b>delay</b> : Number<p class="sub-desc">The number of milliseconds to delay the invocation of the handler after the event fires.</p></li>

handler is <em>not</em> invoked, but the new handler is scheduled in its place.</p></li>
</ul><br>
<p>
<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, {
    single: true,
    delay: 100,
    forumId: 4
});</code></pre>
<p>
<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple handlers.
<p>
<pre><code>foo.on({
    <em>'click'</em> : {
        fn: <b>this</b>.onClick,
        scope: <b>this</b>,
        delay: 100
    },
    <em>'mouseover'</em> : {
        fn: <b>this</b>.onMouseOver,
        scope: <b>this</b>
    },
    <em>'mouseout'</em> : {
        fn: <b>this</b>.onMouseOut,
        scope: <b>this</b>
    }
});</code></pre>
<p>
Or a shorthand syntax:<br>
<pre><code>foo.on({
    <em>'click'</em> : <b>this</b>.onClick,
    <em>'mouseover'</em> : <b>this</b>.onMouseOver,
    <em>'mouseout'</em> : <b>this</b>.onMouseOut,
     scope: <b>this</b>
});</code></pre></div></li>        </ul>
