> I'd like to propose following new high-level transforms.
>  * Intersect
> Compute the intersection between elements of two PCollection.
> Given _leftCollection_ and _rightCollection_, this transform returns a collection containing elements that common to both _leftCollection_ and _rightCollection_
>  
>  * Difference
> Compute the difference between elements of two PCollection.
> Given _leftCollection_ and _rightCollection_, this transform returns a collection containing elements that are in _leftCollection_ but not in _rightCollection_
>  * Commons
> Find the elements that are commons to two PCollection, similar like the Unix
> comm utility.
> Given _leftCollection_ and rightCollection, this transform returns a CommonsResults with following:
>  # elements only in _leftCollection_
>  # elements only in _rightCollection_
>  # elements in both collections
> I would like to work on this changes and submit a PR.
