Separated data and models files

[sayden]

To have a huge schema is not very nice. A better file structure should be achieved to improve quality and comprehension like in this graphql example. https://github.com/sayden/graphql-mongodb-example/tree/master/Models

But it has provoque cyclic dependencies problems in the past when achieved this way and it seems that Babel couldn't manage them well.

Hey sayden, any updates on these cyclic dependencies problems? :)
