>             Project: Flink

>          Components: Scala API

> First cleanup attempt, mostly on Scala code, to follow guidelines from http://docs.scala-lang.org/style:
> 1. Remove return statement from Scala code where it is not necessary (end of method definition)
> 2. Remove extra semicolon (;) from Scala and Java code
> 3. First drop to abide to 100 chars per line for Scala code.
>    Will send another PR for other files as I have encountered.
> 4. Remove parentheses for empty argument methods that do not have side effect
>    (see http://www.artima.com/pins1ed/composition-and-inheritance.html#i1343251059-1)
> 5. Remove unused import statements in Scala code as I have encountered them.
> This is first drop to refactor and cleanup Scala code to see comment/ response from community.
> More PRs for follow up code will come.
