Sherlock initial checkin.

[dkorolev]

Hi guys, here comes Sherlock.

Done:

• Publish() and half of Subscribe().
• WaitableAtomic (this one is from 2014).
• Basic unit tests.
• A hacky HTTP Chunked response server for the data to unblock John.
• README v0.01.

In progress:

• Infinite (chunked) response objects ownership. I'll have to redesign the parameters to Subscribe(), since it should take ownership of the passed in processor in case of detach()-ing the thread.
• RTTI and a test for it.
• Weird HTTP API issue, namely, JSON serializer not working out of the box.

Not done, and will not be done until the first demos take place.

• Timestamps and data monotonicity guarantees.
• Key-ing streams and retrieving them by name.
• Persistence layer.

@deathbaba, @sompylasar, @mzhurovich : PTAL. As always, user-facing API is my primary concern.

Thanks, Dima

@sompylasar , thank you for the comments on the comments!

I've just fixed all of them, could you please look through again?

Have an idea on how to make the ownership part with Join() vs. Detach() clear, will do in the next several hours.

Thanks, Dima

@sompylasar , @deathbaba : PTAL at OptionallyOwned.

I got a dinner invite, will blend OptionallyOwned with Detach()-ing the listeners in ~4 hours.

Thanks, Dima

The code is too complex for me to get the idea and review it effectively. Can merge it though.
