Previously, we were using a static func here because we needed to recursively pass it during initial parsing. However, since we can now pass the initializer, I think it makes sense to simplify the API by directly using an initializer.

Decoding with Root Keys
The easiest way to decode models from JSON is to use the global decode
function: pass the AnyObject variable returned from NSJSONSerialization
directly to decode, and you'll get the model back. However, many times the
JSON for the model is embedded within a root key:
{
"user": {
"id": 1881372911,
"name": "George Senior"
}
}
In this case, you can't use the global decode function because it assumes
the object you're trying to decode is at the root level. To get around this,
first transform the AnyObject into a JSON type, then use the <| operator
to pull out the object and decode it into its model.
let json = JSON(anyObject)
let user: Decoded<User> = json <| "user"
// or
let user: User? = json <| "user"
