* Statistics: add support for percentage unit in addition to time I think, `stddev` statistic is useful, but confusing. What does it mean if `stddev` of `1ms` is reported? Is that good or bad? If the `median` is `1s`, then that means that the measurements are pretty noise-less. And what about `stddev` of `100ms` is reported? If the `median` is `1s` - awful, if the `median` is `10s` - good. And hurray, there is just the statistic that we need: https://en.wikipedia.org/wiki/Coefficient_of_variation But, naturally, that produces a value in percents, but the statistics are currently hardcoded to produce time. So this refactors thinkgs a bit, and allows a percentage unit for statistics. I'm not sure whether or not `benchmark` would be okay with adding this `RSD` statistic by default, but regales, that is a separate patch.
