Serves as a reference harness to get benchmarking started.
Steps to run benchmark:
$ go test -run=^$ -bench=. -count=10
After you grab the output, put the various comparisons
into files before.txt and after.txt then edit those
result names to have a common name e.g.
s/BenchmarkLoggingNoExporter/BenchmarkIt/g
s/BenchmarkNoTracingNoMetricsNoLogging/BenchmarkIt/g
s/BenchmarkLoggingStdlib/BenchmarkIt/g
Now run benchstat:
