Title: Allow settings filename to be passed as a cli option

This resolved issue #195, allowing for `bin/run.sh --settings settings.a.json`. As suggested by @fourplusone, cli args are parsed in their own module, allowing them to be cleanly expanded upon in the future.

Since `-s|--settings` is currently the only option, a `--help` flag is not provided.

(This is a cleaner implementation of pull #455, which I have closed.)
