> 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.
