Box2D Physics port to JavaScript

This won’t be your final library to build your game, but it certainly is useful if you like to slam code!  Thanks David!  You are the best.

This means that if you are considering creating your own WinRT based library in C++ that consumes Box2D could be better used to utilize the already converted library in your HTML5/JavaScript work.  WinRT is designed for Language projection.
