tsz is a fast and eventually more sound TypeScript type checker.

I read in the rules that existing projects do not qualify but I explicitly mentioned that I will be working on this for the hackathon when I signed up. I'm okay if this project is not accepted. It is still a work in progress so it was neither started or completed during this hackathon. But I would love to get more publicity and hopefully contributions to the project anyway. I've been working on this since Jan 1st!
