Description

We're going to enable ZAF SDK to be imported as a Node Module. PR #144 was previously raised, all points make sense.

Since we introduced Typescript we can't import lib/index.js directly. Instead, import dist/zaf_sdk.min.js which are the assets for npm publish.

If you want to install from github, npm install https://github.com/zendesk/zendesk_app_framework_sdk#"wxing/VEG-1404" --save.

import ZAFClient from 'zendesk_app_framework_sdk';
var client = ZAFClient.init();
...

Make sure to commit the latest dist by npm run build each time. Once we move to npm, it can be done via CI/CD.
