Support favorites #7
Description
favorites.getPublicList(docs): User’s publicly-accessible favorites.favorites.getList(docs): Full list of a user’s favorites, including non-public ones.rfavorites.add(docs): Add a photo to user’s favorites.w+favorites.remove(docs): Remove photo from user’s favorites.w+
getList and getPublicList accept per_page (0..500; default 100) and page (n; default 1) parameters for use with large collections of favorites. The <photos> element of the XML response includes a pages attribute indicating how many calls are needed to collect all the favorites for the given per_page, as well as a total attribute that states how many favorites the user has.
For the user’s convenience, I suggest an optional argument along the lines of n_favorites that will automatically make the required number of calls and assemble a unified list. (A more complicated but full-featured alternative would be start and end arguments.)
