Absolute import path aliases

What

• https://stackoverflow.com/questions/38601592/typescript-import-path-alias

Why

• It makes it a lot easier to maintain certain kinds of imports (local lib most common use-case) across an app codebase.

How

• Use a bundler for build / dev #854
• https://github.com/rollup/plugins/tree/master/packages/alias (example, only specifically relevant if we bundle with rollup, though)
• Fix #189, reference dist/index.d.ts in types graphql-nexus/nexus#199 (some insight, we looked at doing it on this codebase)

Instances

• Cannot wrap unknown types in a nonNull(). Saw undefined graphql-nexus/nexus#928 / Resolve typescript path mapping before nexus scans code #927
• Getting Error Type is not assignable graphql-nexus/nexus#855
