add docs for babel 6

[hzoo]

Should probably include es2015 but it doesn't apply for this particular example?

Could this please be reviewed and merged?

@puhastudio Please check your entitlement. This is an open source project, it's Saturday morning, Babel 6 came out 2 days ago, and we have lives. We're not all here 10 minutes after every pull request.

@hzoo Thanks for this! I wouldn't be surprised if people use that as source of truth so it's probably worth adding a link to the blog post (since the docs aren't all updated) or adding something about es2015 preset as well for those using it, even if the example here doesn't.

@zpao I'm sorry, forgot to check dates and times.

[hzoo]

@zpao Yep true that. I'l add a link to the post and include the es2015 preset
