Indent to 2 spaces

I'm too lazy to indent differently for my private projects
and work :-(
Not sure what I did.

I shouldn't keep code out for 2 weeks without committing
Respect the law of Dimiter
Make specs consistent
Continue improving tests
Test bin.index()
Remove YAGNI
Require files in a way that will work in a browser
Conditionally setup root namespace

On the browser it is arguably wrong to keep redefining root
Start writing a metaphor in TODO

Probably this should be in a different file
Use module.exports rather than exports
