/*
* Embedly JQuery
* ==============
* This library allows you to easily embed objects on any page.
*
* Usage:
* ------
* There are two ways to interact with this lib. One exposes a simple method to call embedly directly
*
* >>> $.embedly('http://www.youtube.com/watch?v=LfamTmY5REw', {}, function(oembed){ alert(oembed.title);});
*
* The oembed is either a json object or null
*
* You can also reference it this way, which will try and replace every link on the page with an embed
*
* $('a').embedly();
*
* The Options Are as Follows
*
* {maxWidth : null,
* maxHeight: null,
* urlRe : null,
* method : 'replace',
* wrapElement : 'div',
* className : 'embed',
* addImageStyles : true} //after
*
* http://api.embed.ly/tools/generator - generate your own regex for only sources you want
*
