    To prepopulate the tweet with the random quote, the text in the twitter
    iframe needs to be changed to the quote text:

    Step 1. remove existing twitter iframe (including the <a></a> markup)
    Step 2. Reinsert the markup into the DOM with the fresh quote text
    Step 3. Reload the twitter widget
    Now if user wants to tweet, tweet will be prepopulated with the quote!

    ***************************************************************************/

    var tweetBtn = $("<a></a>")

    .attr("data-size", "large")
    .attr("data-text", tweetText);
    $("#tweetBtn").append(tweetBtn);
