[FLINK-5426] Clean up the Flink Machine Learning library
Hi guys,
I would like to contribute to the Flink ML library. I took the liberty to
clean up some of the code and improve the scaladoc. Beside that I've
implemented #3077 to get more familiar with the Flink API and I would love to
contribute more in the future, in particular the machine learning library.
If you have any questions, please let me know. Let me know if improvements
to the ML library are appreciated in general.

> Hi Guys,
> I would like to clean up the Machine Learning library. A lot of the code in
> the ML Library does not conform to the original contribution guide. For
> example:
> Duplicate tests, different names, but exactly the same testcase:
> https://github.com/apache/flink/blob/master/flink-libraries/flink-ml/src/test/scala/org/apache/flink/ml/math/DenseVectorSuite.scala#L148
> https://github.com/apache/flink/blob/master/flink-libraries/flink-ml/src/test/scala/org/apache/flink/ml/math/DenseVectorSuite.scala#L164
> Lot of multi-line tests-cases:
> https://github.com/Fokko/flink/blob/master/flink-libraries/flink-ml/src/test/scala/org/apache/flink/ml/math/DenseVectorSuite.scala
> Mis-use of constants:
> https://github.com/apache/flink/blob/master/flink-libraries/flink-ml/src/main/scala/org/apache/flink/ml/math/DenseMatrix.scala#L58
> Please allow me to clean this up, and I'm looking forward to contribute more
> code, especially to the ML part. I've have been a contributor to Apache Spark
> and am happy to extend the codebase with new distributed algorithms and make
> the codebase more mature.
> Cheers, Fokko
