Acess to global function prototypes for extension

Hi Everyone,

I've been using envjs with some success as a unit testing tool. My app makes use of ExtJs, which makes use of the DOM Range object. The I added the Range implementation below. I know the goal is to have a pure JavaScript implementation, and my createRange function is not that. But adding this allowed me to do some simple function testing with ExtJs, and so I figured I'd share.

  DOMDocument.prototype = {
    get nodeType(){
        debug('DOMDocument : nodeType');
      return 9;
    },
    createRange : function() {
        debug('DOMDocument : createRange');
        return new Range(this);
    },

    this._dom = node;
