Title: Add explicity for EventStream

* show it explicity by NotImplementedError that EventStream is abstract class
* add comments to describe difference between ArrayEventStream and MultiEventStream
* remove comment-outed methods of ArrayEventStream to break interoperability of EventStream
* remove comment-outed IoEventStream:
* that is not implemented and is not going to be implemented
* that is danger because it require io-stream to be opened until the EventStream is destructed
