1293 - start porting the chessboard app over

Just to put all our new test primitives through their paces, and iron
out any kinks.

Just the one chessboard scenario is taking 1.5-2.5x all the tests we've
written so far. But we're starting from a faster baseline, that was the
point of the C++ port. I also have -O3 optimizations in my back-pocket.
