> 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);
