A repository might represent a region, like "Anywhere City",
or a major client or contract, like "Midwestern Charter Network.
Within that repo you would have a subfolder for each analysis project.
This function creates such a subfolder and populates it with folders and a README.
To use: within an existing repository on Bitbucket, set your your working
directory to that folder and run this function to create a sub-folder.
Use setup_repo()
in a blank new repository to add the first project subfolder
and create the RProject and .gitignore files. Add subsequent analysis project folders
with this function.
