Create a branch to demonstrate how to use this with Typescript

[ccaspanello]

I like to use typescript with my projects and having a typescript branch would help other developers get started.

Here is my attempt at converting everything. There were a few places I used any or //@ts-ignore because I didn't want to refactor too much and deviate from non-typescript way.
