[SPARK-16692] [ML] Add multi label classification evaluator, DataFrame
Add the multi label classification evaluator to DataFrame, ML
Also add the multilabelClassifcationSuite.scala unite test.
A multilabel classification problem involves mapping each sample in a
dataset to a set of class labels. In this type of classification problem, the
labels are not mutually exclusive. For example, when classifying a set of news
articles into topics, a single article might be both science and politics.
