This needs a "package" statement at the top -- in Scala, just having it in a directory isn't enough. Also, make the package be `org.apache.spark.mlllib.api.python` instead of just `org.apache.spark.mlllib.api` (you'll need to git move the file into there). Once you do this you'll also have to make some changes on the Python side to access the class from this package -- I believe it's possible to alias it to save typing, but look at some of the other ones we import there.
