Paris Carbone updated FLINK-1344:
---------------------------------
    Summary: Add implicit conversions from scala streams to DataStreams  (was: Add support for lazy collections and scala streams for functional source definitions)

> Source definitions in the scala-api pass a collector to the UDF, thus enforcing an imperative style for defining custom streams. In order maintain a purely functional coding style in the streaming scala-api while also adding some interoperability with scala constructs (ie. Seq and Streams) 
> [UPDATE] Since there is already a fromCollection(Seq) function we can simply add an implicit conversion from Seq[T] to DataStream[T]. 
> (An additional idea would be for sinks could also support wrapping up flink streams to scala streams for full interoperability with scala streaming code.)
