Gauge: a clone of criterion

This is a clone of criterion with a code / dependencies on a diet. It works the same way as criterion for outputing to terminal benchmark data.

features compared to criterion

missing:

• JSON export
• HTML/javascript pages
• Glob benchmark matching

Added:

• Small condensed output (-s or --small)
• Raw measurements dumping (CSV)

Future Feature Plan

• Remove further dependencies
• storing benchmarks data in CSV and JSON
• Add a standalone program taking benchmark data files and rendering to html/javascript/graphs
• Make the library more useful as a standalone library to gather benchmark numbers related to functions in a programatic way

Small mode

It's hard to compare many benchmarks with criterion, so gauge has a --small output:

identity                                 mean 41.65 ns  ( +- 2.246 ns  )
slow                                     mean 163.9 ns  ( +- 9.683 ns  )
