A tool for gathering and analyzing benchmark data. The idea is that
you should create a series of commits representing various changes
whose effects you would like to measure. You can run cargo-chrono bench for each one and it will run cargo bench and accumulate the
results into a CSV file. Then you can run cargo-chrono plot to see
the results plotted and hence get a feeling for the effect of each
commit.
Still very early and hacky, but very useful! Note that the plotting feature requires gnuplot to be installed.
