Webmaker auth client

This is the client-side library that adds support for Webmaker Login to your app. In order for it to work, you will need the following on your app's server:

express
webmaker-auth, the sister node module for this library

If you choose to use the create user form assets included in this package, you will also need node-webmaker-l18n for localization and nunjucks for server-side rendering.
