Relay implementation

It would be nice to support Relay implementations in order to simplify pagination of results.

Can you give more information about this?

You can see information about Relay here. I saw that Relay is already supported in the server-side repository but not in this one. I have created a repository supporting this. It also features building query strings following an expression-based approach (similar to Linq).

@pekkah Do you have more information about this? I mean, the "Relay Servers" change the spec at protocol level or is just some hight end API?
