Hello and thank you for your contribution!
Due to an excessively long queue of pull requests that have become stale, we are "declaring bankruptcy" and closing all PRs opened before May 1, 2016. If you'd still like to merge this code in, please open a new PR that has been merged and rebased with the master branch.
Going forward, we are committing to review or merge all PRs on a regular basis so this bankruptcy will not occur again. We apologize for the incovenience and hope you will continue to contribute to DefinitelyTyped in the future.
Thanks The TypeScript and DefinitelyTyped teams
