-- Why not just create a tag from the branch via git? Because we want to add the build artifacts to the GitHub relase as attachments (for users neither using npm or bower).

Created with browserify's `--require` parameter and intended to be used (required) from other browserified modules, which were created with `--external traverson-angular`. This build could be used if you use browserify but do not want to bundle traverson-angular and Traverson with your own browserify build but keep it as a separate file.
 * `traverson.external.js`: Non-minified require/external build, same as before, just larger.
