> There is no class in Spark MLlib for measuring the performance of multi-label  classifiers. Multilabel classification is when the document is labeled with several labels (classes).
> This task involves adding the class for multilabel evaluation and unit tests. The following measures are to be implemented: Precision, Recall and F1-measure (1) based on documents averaged by the number of documents; (2) per label; (3) based on labels micro and macro averaged; (4) Hamming loss.
