Versioned Controllers

[calebkleveter]

PayPal has started rolling out version 2 of their REST API, so we should handle both version 1 and version 2. The current structure doesn't allow for this, so we basically need to redesign how we handle API resources.

In the past, we have done something like this:

let payments = try request.make(Payments.self)
let authorization = payments.get(authorization: id)

Now we will do something like this:

let authorizations = try request.make(PayPal.API.self).v2.payments.authorizations
let authorization = authorizations.details(for: id)
