    /*--------------------------------------------------------------------------
    This pulls in tweets gathered from the WordPress plugin
    ouath-twitter-feed-for-developers and converts them into
    an <article> tag
    It takes retweets into account and then updates links within
    the tweet text to convert urls, tags, and hashes into anchor
    tags
    it is based slightly on a script found here:
