BB pipeline paper plots

To add a new plot:

• Add all necessary data to the data folder. Be minimalistic (e.g. if you are taking the mean and standard deviation of 500 sims and only using that in the plot, then it's best to just upload a file with the mean and standard deviation, than 500 files with all the sims).
• Add a script to plot_scripts that uses those data to generate a plot. It should be callable from the root directory. See plot_scripts/example.py for an example.
• Do not add the plot this generates to the repo. pdf files are not easy to track for git, and they end up taking a huge amount of space.
