Import individual types from within another grapqhl file

[corbpaul]

While its possible to import everything into another .graphql using the import comment#import "./personSchema.graphql", is it possible to import individual types?

This is similar to graphql-import where they would have # import Person from "./personSchema.graphql"

This package is based upon graphql-tag/loader, but maybe it's time to move to a more advanced importer like graphql-import. I'll check if all current features will be supported and if it's an easy switch.

PRs welcome of course.
