Convenient BDD specs for Angular

# Development

To build the README document, run unit tests and linter

    npm run build

To run all unit tests (against different Angular versions)

    npm test

To keep a watch and rerun build + lint + tests on source file change

    npm run watch

For now, all source is in a single `ng-describe.js` file, while the documentation
is generated from Markdown files in the `docs` folder
