Use this to make a wizard to walk through set-up steps
gcs_setup()
This function assumes you have at least a Google Cloud Platform project setup, from which it can generate the necessary authentication keys and set up authentication.
It uses gar_setup_menu to create the wizard. You will need to have owner access to the project you are using.
After each menu option has completed, restart R and reload the library and this function to continue to the next step.
Upon successful set-up, you should see a message similar to Successfully auto-authenticated via /xxxx/googlecloudstorager-auth-key.json and Set default bucket name to 'xxxx' when you load the library via library(googleCloudStorageR)
