Publish types

[TimonLukas]

Hey! I've developed a number of projects based on the Watson IoT platform. I used to always use the ibmiotf package, but it seems like these days it would be recommended to use this package instead.

Sadly it's quite difficult to use, since the documentation is mostly non-existent, and no types exist for the interfaces. I've written my own definitions for the methods I need in my TS projects (see gist). If types like these were published, it would already be a lot easier to work with the library, since they at least help with things like auto-completion.
