Please add a license to this repo

[dhruv]

Thank you for making your code available! Could you please add an explicit LICENSE file to the repo so that it's clear under what terms the content is provided, and under what terms user contributions are licensed?

Per GitHub docs on licensing:

Generally speaking, the absence of a license means that the default copyright laws apply. This means that you retain all rights to your source code and that nobody else may reproduce, distribute, or create derivative works from your work. This might not be what you intend.

Thanks!

As an update, it seems like most of the Angular ecosystem uses the MIT license.
