 * The class and trait hierarchy for logistic regression model summaries was changed to be cleaner
 and better accommodate the addition of the multi-class summary. This is a breaking change for user
 code that casts a `LogisticRegressionTrainingSummary` to a

 method. See [SPARK-17139](https://issues.apache.org/jira/browse/SPARK-17139) for more detail 
 (_note_ this is an `Experimental` API). This _does not_ affect the Python `summary` method, which
 will still work correctly for both multinomial and binary cases.
