------------------------------------

[~amaliujia] I have created PR [1]. Can you please help me review it?
Should we remove [2] class, it is unused, but is public.

> 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_
>  
>  * Except
> 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_
>  * Union
> Find the elements that are either of two PCollection.
> Implement IntersetAll, ExceptAll and UnionAll variants of transforms.
