Eliminate Scope/ScopeID, separate API from SDK for metrics/stats (#48)

Browse Source 
* Move scope.Active to trace.CurrentSpan

* Remove scope / does not build

* Global tracer

* Checkpoint

* Checkpoint

* Add key/key.go for key.New

* Comments

* Remove more EventID and ScopeID

* Use Handle to describe static objects

* TODOs

* Remove empty file

* Remove singletons

* Update TODOs

* TODO about map update

* Make stats package option aliases (like key has)

* Rename experimental/streaming

* streaming SDK builds w/ many TODOs

* Get the examples building

* Tidy up metric API / add interface check

* Remove logic from the registry; this is now a placeholder
