configure NODE_PATH?

Hey,

we're using something similar to https://gist.github.com/branneman/8048520#52-only-while-executing-node to prevent having to use long, relative paths when importing/requiring modules.

Is there a way to make filing cabinet aware of such a situation? I'm trying to build a dependency graph for a project that uses `NODE_PATH=src` and would like to be able to resolve something like `import Foo from 'components/Foo'` to `/absolute/path/to/project/src/components/Foo.js`

The issue names no files or tests. Start by tracing filing cabinet's module-resolution entry point and existing path-resolution behavior, then verify it with a project using NODE_PATH=src; it is done when imports such as components/Foo resolve to the corresponding file under the configured source path.
