## 
## \brief
## Clone various NWM repositories.
## 
## \desc
## Clone repos from GitHub. Includes CLI option for using SSH (for r+w, requires credentials) or HTTPS (for read-only, no credentials required).
## Includes CLI option for a shallow (depth 1) clone or full clone. It will not alter the state of existing repos on your disk
## (for each clone, it skips if the folder already exists on disk).
##
## Uses OS env var `REPOS_COMMON_ROOT__HOST` from `config.bashrc`.
## 
## Has 2 positional arguments and 0 named arguments.
## 
## \option SSH_OR_HTTPS
## Required. Specify to clone via SSH (for read-write) or via HTTPS (for read-only). Choices: `["ssh", "https"]`
## 
## \option SHALLOW_CLONE
## Optional. Specify to perform a shallow (`--depth 1`) clone or a deep clone. Choices: `["full", "shallow"]`. Default: `"full"`
## 
## \usage ./setup_clone_repos.sh ssh
## \usage ./setup_clone_repos.sh https shallow
