    When a bundle is partially completed, the unprocessed elements must be
    placed in a new bundle to be processed at a later time. The bundle in
    which they are processed should also have identical properties to the
    bundle which the elements were initially present in.
    
    withElements provides a simple way to create a "copy" of a bundle that
    contains different elements.

> DirectPipelineRunner currently runs over bounded PCollections only, and implements only
a portion of the Beam Model.
> We should improve it to faithfully implement the full Beam Model, such as add ability
to run over unbounded PCollections, and better resemble execution model in a distributed system.
> This further enables features such as a testing source which may simulate late data and
test triggers in the pipeline. Finally, we may want to expose an option to select between
"debug" (single threaded), "chaos monkey" (test as many model requirements as possible), and
"performance" (multi-threaded).
> more testing (chaos monkey) 
> Once this is done, we should update this StackOverflow question:
