/*
// Tumblr Widget for displaying lists of posts
NOTES:

Maybe you should use this widget by doing this:

1. Stick a containing div somewhere:

<div id="tumblelist"></div>

2. Include the script

<script type="" src=""></script>

3. Run and configure

<script>
	$('#tumblelist').tumbletag({ type: 'link' });
</script>

* Support all the tumblr api parameters?
