//- RSS Feed
    =========================
    Your blog's RSS feed in XML format. It loops through your posts and includes
    them as partials to make it possible to display your content via RSS. If you
    don't want to include your full blog posts in the RSS feed, replace the 
    partial with an excerpt or summary. Just add this to your post meta data.
    =========================

//- Function to convert date to valid XML pubDate
    Example here: http://www.w3schools.com/xml/rss_tag_pubdate_item.asp

-   function convertPubDate(date) {
-       var date = new Date(date);
-       var pieces = date.toString().split(' ');
-       var offsetTime = pieces[5].match(/[-+]\d{4}/);
-       var offset = (offsetTime) ? offsetTime : pieces[5];
-       var parts = [ pieces[0] + ',', pieces[2], pieces[1], pieces[3], pieces[4], offset ];
-       return parts.join(' ');
-   }
