REPL: Source map viewer

[hzoo]

EDIT: http://sokra.github.io/source-map-visualization/

Would be interesting to be able to know how different the input/output source is from Babel. Like what if you could see visually the difference of async function a() {} and the output? You could calculate the bytes change, and even suggest a change in config (loose mode, different transform, target different browser) and the % difference in size

My feature request would be a source map output view. It would be great to easily see the maps that babel creates for different configs

Similar to https://twitter.com/left_pad/status/885547523233984512 - we should integrate this too @boopathi

So far as I can tell, this is redundant with #65. Safe to close this one?

Only other source map tool I remember is http://sokra.github.io/source-map-visualization/

Ah~ I didn't realize this ticket was about that. I thought this was just saying we should add source maps to the output (like I've done here, although you may need to use an incognito link since it's got some caching).
