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.
