* Removed outdated "guide to use" in comments in favor of README
* BC break: snippets.permalink now has access to req object and takes a callback. However note simpler approach described next.
* You can avoid calling snippet.permalink yourself more easily now. snippet.get()'s "permalink" option can now take a page object instead of the boolean value `true`. If you pass a page object, all of the returned snippets are permalinked to that page in the .url property. If you just pass `true` then, as always, the best page is found for each snippet via the usual algorithm.
* Added snippets.getOne(), a convenience wrapper for snippet.get() which behaves as you would expect
* Removed findBestPageForMany in favor of addUrls and, better yet, just passing { permalink: true } or { permalink: req.bestPage } as an option to snippets.get
