TODO

User should be able to list categories and feeds.
User should be able to unsubscribe from a feed.
User should be able to subscribe to a feed under a specified category.
User should be able to move a feed under a category.
- Can always unsubscribe then resubscribe in that location, if the API lacks a "move feed" equivalent.
User should be able to add a category.
- API might be lacking entirely here.
User should be able to recursively list categories and feeds.
- We could be smarter, but a first pass should just recursively call our non-recursive list function.
