Yay build tools!!!

I figured you have the most experience with this @DannyBlueDesign

[Nevraeka]

Maybe http://webpack.github.io. @pertrai1 might have some suggestions as well on this.

@Nevraeka @DannyBlueDesign I do think that webpack brings a great deal to the table.

@pertrai1 what does webpack bring that is better than 6to5 or straight up traceur? I honestly don't know for sure but webpack does look good. Anything to limit the runtime dependencies is good. Something like system.js seems to favor that approach but that sounds slower and less performant, no?

I have no experience with any of these except traceur and it's very little at that :(
