ExecutionEnvironment.scala, UnionOperator.java and Graph.java have a lot of
whitespace/formatting changes. This makes it hard to see the actual changes to
functionality.
None of the methods in the new Scala code have comments/Scaladoc.
Especially the methods on Graph.scala, these should have documentation, similar
to the methods on Graph.java.
Other than that, this looks good. I especially like that basically half of
the new files are test cases. :+1:
Could someone from the Graph side ( @vasia, @andralungu ) please chime in
on this.
