Copied "info" JSON from Chrome's network tab while inspecting the Petstore example since I can't find a link on the official documentation.

Allow SWAGGER_SETTINGS['info'] to be used to configure swagger, and copy/paste document it.
I think the "info" dictionary / namespace is enough to warrant the differently styled dictionary keys, though someone else might prefer to take the time to make_it_pythonic instead of camelCased, and maintain it over time - I don't care much either way.
Default to empty strings instead of Petstore example for backwards compatibility.
The title and description are "required", so we should probably provide them instead of an empty dictionary as suggested earlier.

Thanks @ariovistus

Looks like there is a 2.0 Swagger spec present, so the 1.2 should be stable enough to document here - the URL is unlikely to break.
