Delta Requests

While building the initial API endpoints we are keeping track of the server knowledge attributes so that we can eventually do paginated requests.

One way to implement this in a clever way is to not expose it, but make the wrappers enumerables and give them `each` methods so that we can use normal Array-like abilities. Would want to rename them to `*Stream` or something that informs the user that they are similar but different.

Start by reviewing the existing API endpoint wrappers and the server knowledge attributes mentioned in the issue. Clarify the pagination design, then define how wrappers should support each and whether their names should change to *Stream; done means the chosen interface is implemented consistently.
