hxp2js

=======
After evaluating a few other physics libraries, I am now in favour of Nape and it works well with pixi.js. Click here for a quick demo and source code.

I will not be actively maintaining these externs anymore, so if anyone is interested please let me know and I will add them as collaborators.

Externs of p2.js for Haxe - A Javascript 2D physics library.

``haxe
haxelib install p2js
`
Please note that this is an alpha release and the development/testing is still in progress.
