v0.0.1-beta.20

Features

• all: Update to Angular 4, material 2 beta 3 (#23) (690c429)

BREAKING CHANGES

• all: This commit also removes a dependency on AsciiDoc wrapper project in favor
  of (now working) direct npm install asciidoctor.js.

This requires loading asciidoctor.js into the page from your
index.html file, and referencing that file out of node_modules
in your angular-cli.json file.

Warning: As of the AsciiDoctor.js 1.5.5 preview release, adding the
asciidoctor.js file into your page will cause e2e testing to break
with a stack overflow error.
