This is the polished version.
1. The old merge() method in StreamsBuilder has been removed,
2. The merge() method in KStreamBuilder was changed so that it would use the single variable argument
rather than several variable arguments in the KStreamImpl implementation
3. The merge() method in KStream has been declared as final and tests have been added to test correctness.

minor fixes
I found several minor issues with the Kafka Streams tutorial:
* Some typos
* "As shown above, it illustrate that the constructed ..." instead of "As shown above, it illustrate_s_ that the constructed ..."
* "same as Pipe.java below" instead of "same as Pipe.java _above_"
* Wrong class name in the `LineSplit` example
* Incorrect imports for the code examples
* Missing `import org.apache.kafka.streams.kstream.KStream;` in `LineSplit` and `WordCount` example
* Unnecessary (and potentially confusing) split by whitespaces in the `WorkCount` class (the split into words happened already in `LineSplit`)

The iterator interface usage has some examples missing explicit close operation after usage. We should remind the user to do so because un-closed iterator will leave the underlying file descriptor open, thus eating up memory.
