> In several places (LogReg, LinReg, SVC) in Spark ML, we collect summary information about training data using {{MultivariateOnlineSummarizer}} and {{MulticlassSummarizer}}. We have the same code appearing in several places (and including test suites). We can eliminate this by creating a common implementation somewhere.
