@bafolts I tried to find a configuration for our webpack to allow also usage of our code as a module. But I fail. And after studying other repositories like TypeScript and tslint, I realize that none of them uses bundler like webpack. At most, they use typescript togheter with gulp for compilation. And leave all the files separated at the end of the build. Which, now I believe, is the right way.

That makes sense. A tool like webpack makes sense more if packaging for the web.

This still looks fine to merge to me.
