Cabalize examples

This would need to have enough flags to deal with the different meta-par resources.

I think we tentatively decided on flags rather than package fragmentation for this particular case.

[Adam C. Foltzer]

So, we should document the -DPARSCHED=... interface, but then provide flags for sensible defaults?

[Ryan Newton]

Good point... in general cabal flags enable us to turn on and off certain tests (e.g. no GPU tests).

But I don't think we can obsolete the -DPARSCHED method for doing the full NxM testing.

Done, with a fallback for quicker builds via the benchmark.hs script
