@maximo1311 This PR adds a small file to set up "staged dependencies". We don't use this functionality in the package but this file helps some of the automated checks run more efficiently since the environment can be saved and reused between checks.

Staged dependencies is useful when you depend on another package that is also in development, so you need to get the latest version from git not from CRAN.
