Transformation fails when it encounters a hashbang

[appsforartists]

If I try to use my-local-ip (which starts with #! /usr/bin/env node), I get this error:

Error: Error transforming /Users/screencasting/Desktop/ambidex-example/node_modules/my-local-ip/index.js to JSX: Error: Parse Error: Line 1: Unexpected token ILLEGAL

@dominictarr thinks you should have a regex to filter out hashbangs before transformation.
