    Description

      `VectorSlicer` takes a vector column and output a vector column with a subset of features.

      val vs = new VectorSlicer()
  .setInputCol("user")
  .setSelectedFeatures("age", "salary")
  .setOutputCol("usefulUserFeatures")

      We should allow specifying selected features by indices and by names. It should preserve the output names.
