A user can now add another user to a location

* i was able to generate a random password for the new user
* for now that password is displayed in the terminal via a dispaly method
* the password will soon be emailed to the user
Still just not thrilled by the naming. You could potentially do something like `resources :user, only: [:create, :new], controller: :local_users`

This way your routes look like location_users_path
