Delta Requests

[jaredsmithse]

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.
