Initializes a new feedtosis library.  It must be initialized with a valid URL as the first argument.
 A following optional +options+ Hash may take the arguments:
   * backend: a key-value store to be used for summary structures of feeds fetched.  Moneta backends work well, but any object acting like a Hash is valid.
   * retained_digest_size: an Integer specifying the number of previous MD5 sets of entries to keep, used for new feed detection
 Retrieves the latest entries from this feed.  Returns a Feedtosis::Result
 object which delegates methods to the Curl::Easy object making the request
 and the FeedNormalizer::Feed object that may have been created from the
 HTTP response body.
