box2dnode available

I finished my first pass at a Box2D port for nodejs. It is available at http://github.com/jadell/box2dnode.

The module was constructed fairly easily by combining the files from Jonas Wagner's Javascript port of Box2DFlash into one large file, then exporting all the classes using

exports.b2ClassName = b2ClassName;

Pretty simple. Next step is to figure out how to turn mouse movement into forces that act on the various entities on the game board.
