Code Flowchart

[Hussein-Mahfouz]

This is a description of the code pipeline that should be updated regularly. Ideally, the whole pipeline will be run through the build.R file. I should also check targets to avoid running cripts unnecessarily.

I should also move this to the main readme of the repo

Purple is functions used throughout. Green are scripts. Orange border indicates WIP

targets has a steep learning curve but does pay off.
