Move to yargs

[kentcdodds]

Commander is cool and all, but there's some hacky things we have to do to get our CLI to do what we want. It'd be sweet to use yargs which is much more flexible.

All changes should happen in here. Should hopefully be able to just use it similar to how I've used it in split-guide here 👍

That's a pretty solid starting point! 👍
Some things that should change here as well, from the looks of it, right?

[kentcdodds]

Yes, probably so...

I actually found nomnom to be the best. Just in case you've never heard of it http://npm.im/nomnom

I've never used nomnom, but I have used yargs and liked it pretty well. It's also much more widely used. I think I'd like to stick with that one personally. What do you think @sxn?

Hm. Actually I hadn't played around with either of those, so I can't form an informed opinion. I'll briefly look into both before diving in and come back. Without looking into them I'd probably choose {{yargs}} just because there would be at least one person who knows this codebase and the library we'd be introducing. :D
