How to publish vis.js

This document describes how to publish vis.js.

Build

Change the version number of the library in both package.json and bower.json.
Open HISTORY.md, write down the changes, version number, and release date.

Build the library by running:

  npm prune
  npm update
  npm run build

This generates the vis.js library in the folder ./dist.

Test the library:
```
  npm test
```
Open some of the examples in your browser and visually check if it works as expected.

Commit the changes to the develop branch.
Merge the develop branch into the master branch.
Push the branches to github
Create a version tag (with the new version number) and push it to github:
```
  git tag v3.1.0
  git push --tags
```

Copy the dist folder from the master branch to the github-pages branch.
Copy the docs folder from the master branch to the github-pages branch.
Copy the examples folder from the master branch to the github-pages branch.

Create a packaged version of vis.js. Go to the master branch and run:

  zip vis.zip dist docs examples README.md HISTORY.md CONTRIBUTING.md LICENSE* NOTICE -r

Move the created zip file vis.zip to the download folder in the github-pages branch. TODO: this should be automated.
Check if there are new or updated examples, and update the gallery screenshots accordingly.
Update the library version number in the index.html page.
Commit the changes in the gh-pages branch.

Switch to the develop branch.
Change version numbers in package.json and bower.json to a snapshot version like 0.4.0-SNAPSHOT.
