Using a custom Babel config

This example features:

• An app using proposed do expressions.
• It uses babel-preset-stage-0, which allows us to use above JavaScript feature.
• It uses '.babelrc' file in the app directory to add above preset.

Most of the time, when writing a custom .babelrc file, you need to add next/babel as a preset.
