mean one registry

Milestone: mean-one-registry

1. Investigate using npm as the registry
2. meanio core code able to use an npm package as a mean module
3. modules front end dependency handling (install time)
4. Is this just dependent on the package itself?
5. May want to wait on possible update to webpack/browserify/etc?
6. Base functionality of registry should keep track of mean packages and repositories they’re in.
7. mean package information should probably come from mean.json not package.json (things like name, repository etc)
