moar modules

[jonathanong]

any reason not to use the flatten module? implementation isn't the best but hey.

decode_param would be nice as a jshttp module since i tend to use that often. maybe use http-errors for it if we can somehow make it a TypeError.

refactoring w/ path-match would be nice, but you did add extra stuff

I looked at the flatten module and do intend to use it, but just wanted to give another look over the implementation/get the tests in order before changing things.

Ideally this needs to be more modules, yes. Even the route stuff should be a separate module.

i like your style
