Analyze how a Git repo grows over time

Some scripts to analyze Git repos. Produces cool looking graphs like this (running it on git itself):

How to run

1. Run pip install -r requirements.txt to install dependencies
2. Run python analyze.py <path to repo> (see python analyze.py --help for a bunch of config)
3. Run python stack_plot.py cohorts.json which will write to stack_plot.png
4. Run python survival_plot.py survival.json which will write to survival_plot.png (see python survival_plot.py --help for some options)

If you want to plot multiple repositories, have to run python analyze.py separately for each project and store the data in separate directories using the --outdir flag. Then you can run python survival_plot.py <foo/survival.json> <bar/survival.json> (optionally with the --exp-fit flag to fit an exponential decay)
