This PTransform Reifies and accumulates all panes produced for each
window, outputting a single pane per window at the time the window is
Garbage Collected.
For use in PAssert, to match over the final contents of each window.

> Key: BEAM-155

> Project: Beam
> Issue Type: Improvement
> Components: sdk-java-core
> Reporter: Thomas Groh
> Assignee: Thomas Groh
>
> This consists of reifying the output windows and panes, and running asserts
> per-window about the contents of panes.
> This includes aggregated matching and final pane matching, e.g.
> PAssert.that(output).byOnTimePane().hasOutputElements(foo, bar);
> // For discarding mode - could have emitted (say) [spam, eggs], [spam], [],
> [sausage], []
> PAssert.that(output).byFinalPane().hasOutputElements(spam, eggs, sausage,
> spam);
> // For accumulating mode without late data
> PAssert.that(output).finalPane().containsInAnyOrder(spam, eggs, sausage,
> spam);
> // For accumulating mode with late data
> PAssert.that(output).finalPane().containsInAnyOrder(foo,
> bar).mayAlsoContain(baz, rab);
