How to turn on tracking by User ID?

Hi, I can't seem to find a method responsible to setting the GA User ID. Is it not implemented, or am I missing something?

I am also looking to track User ID. It seems it is a new feature. Has it been implemented? If not, then any chance of it being available in any updates in the near future?

This is the feature that I am talking about-

Tracking UserID should be a simple as adding an additional parameter to the request "uid" which will contain whatever user identifier is provided by Windows/Windows Phone.

At this point in time, the SDK does not support this parameter in any requests, but if you wanted to hack up the SDK to add it, it would be relatively simple to just follow a pattern similar to the way the Device Id (passed in as the "cid" parameter) is set and expose a method somewhere on the tracker/config to set it.
