 // This program benchmarks the theoretical throughput of the cast library.
 // It runs using a fake clock, simulated network and fake codecs. This allows
 // tests to run much faster than real time.
 // To run the program, run:
 // $ ./out/Release/cast_benchmarks | tee benchmarkoutput.asc
 // This may take a while, when it is done, you can view the data with
