title: Getting flask-restful routes from within a blueprint
body: <p>Is there a way to get the routes defined in a blueprint? I know this (<a href="http://flask.pocoo.org/snippets/117/" rel="nofollow">http://flask.pocoo.org/snippets/117/</a>) snippit exists, but requires to have the app initalized to use url_map. Is there a way to view the routes without an application? I'm developing an api with flask-restful and I would like to display the routes from within the blueprint without the app to keep it self contained.</p>
