Embed Github contributions graph in website

I wrote a JavaScript library to do that: github-calendar.

Here is an example how to use it:

<!-- Prepare a container for your calendar. -->
<script
  src="https://cdn.rawgit.com/IonicaBizau/github-calendar/gh-pages/dist/github-calendar.min.js"
>
</script>

<!-- Optionally, include the theme (if you don't want to struggle to write the CSS) -->
<link
  rel="stylesheet"
  href="https://cdn.rawgit.com/IonicaBizau/github-calendar/gh-pages/dist/github-calendar.css"
/>

<!-- Prepare a container for your calendar. -->
<div class="calendar">
    <!-- Loading stuff -->
    Loading the data just for you.
</div>

<script>
    new GitHubCalendar(".calendar", "your-username");
</script>

Here you can see it in action:

Basically, since we need cross domain requests we need a proxy. It makes a request to GitHub profile page (github.com/<user>) and then brings back the needed stuff from there.
