Meteor integration

Hi Kumail,

I'm a Meteor.js dev and volunteer package maintainer for Meteor. Flakes is awesome for business, internal applications, and adding it to Meteor's ecosystem will expose it to many new devs (Meteor has 20k+ stars on GitHub), likely bringing in new testers and contributors.

This PR will let you directly publish updated versions of the library as they become available. All you have to do is create an account at https://meteor.com/ (click SIGN IN, then Create account). After you've done that, please let me know the name of the account, and I'll add you as a maintainer.

I've already published the [current version](https://atmospherejs.com/flakes/flakes) of the package on Atmosphere (Meteor's package directory). When you release new versions, you can run `meteor/publish.sh` to publish new versions to Atmosphere. If meteor is not installed on your system, it will be installed when you run the script. That will work out of the box on Mac OS X and most popular Linuxes.

If you're curious, you can see an overview of this initiative (initiated by @dandv) [here](https://github.com/MeteorCommunity/discussions/issues/14).

Thanks & kind regards,
Stephan, flakes and Meteor fan
