-------------------------------------------------------------------

The initial implementation can be found here: https://github.com/avulanov/spark/tree/annclassifier.
It encodes the class label as a binary vector in the ANN output and selects the class based
on biggest output value. The implementation contains unit tests as well. 

The mentioned code uses the following PR: https://github.com/apache/spark/pull/1290. It is
not yet merged into the main branch. I think that I should not make a pull request until then.

> Implement classifier based on artificial neural network (ANN). Requirements:
> 1) Use the existing artificial neural network implementation https://issues.apache.org/jira/browse/SPARK-2352,
https://github.com/apache/spark/pull/1290
> 2) Extend MLlib ClassificationModel trait, 
> 3) Like other classifiers in MLlib, accept RDD[LabeledPoint] for training,
> 4) Be able to return the ANN model
