> The file {{/mllib/src/main/scala/org/apache/spark/ml/recommendation/ALS.scala}} currently contains four top-level classes that span 1,500+ lines.  To make the file easier to navigate, and to bring it in line with the [Scala style guide|http://docs.scala-lang.org/style/files.html], I propose we split it into four files holding their respective classes: {{ALS.scala}}, {{ALSParams.scala}}, {{ALSModel.scala}}, and {{ALSModelParams.scala}}.
