This allows PCollections that have upstream triggers that fire multiple
times to assert the contents of panes with specific timings, rather than
restricting the trigger to fire only once.

> Support asserting the contents of windows and panes in PAssert
> --------------------------------------------------------------
>
> Key: BEAM-155
> URL: https://issues.apache.org/jira/browse/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);
