auto-nginx - for setting up a simple nginx config for further tweaking

this is a work under construction. i have yet to finish this, but it is a simple start for someone who have never created a script longer than 4 lines before.

project plan:

• actually learn to hack together something that looks like a bash scripts
• hopefully have a finished configuration in the end

what this is supposed to do when it is finished:

• create a simple nginx reverse-proxy configuration, ready for deployment
• be able to run certbot and add ssl encryption to the reverse-proxy
• support arguments to the command, for setup
• optionally: harden the configuration to secure your precious server
