Support basic functionality with GroupByKey and ParDo.

Added support for grouping operations.

Added checkpointDir option, using it before execution.

Support Accumulator recovery from checkpoint.

Streaming tests should use JUnit's TemporaryFolder Rule for checkpoint 
directory.

Support combine optimizations.

Support durable sideInput via Broadcast.

Branches in the pipeline are either Bounded or Unbounded and should be 
handles so.

Handle flatten/union of Bouned/Unbounded RDD/DStream.

JavaDoc

Rebased on master.

Reuse functionality between batch and streaming translators

Better implementation of streaming/batch pipeline-branch translation.

Move group/combine functions to their own wrapping class.
