Lib.rs

Run function repetitively and prints out aggregated result.

Differences from other benchmark library:

• Do not enforce measuring "wall time". It could be changed to "CPU time", "memory usage", etc.
• Do not run only the benchmark part repetitively. For example, a benchmark needs some complex setup that cannot be reused across runs. That setup cost needs to be excluded from benchmark result cleanly.
• Minimalism. Without fancy features.
