_module_base_dir='assets/js/modules'
_module_path="${_module_base_dir}/${_module_name}"
Bash Submodule Commands
cd "<your-git-project-path>"
git checkout gh-pages
mkdir -vp "${_module_base_dir}"
git submodule add\
-b master --name "${_module_name}"\

git submodule update --init --merge --recursive
git add .gitmodules
git add "${_module_path}"
## Add any changed files too
