Throws reference error when using Browserify (assuming will also throw error with other bundlers?)

Looks like d4 variable isn't available inside subsequent closures after the first when compiling with Browserify. As a quick-fix, I declared d4 variable outside all closures. Thoughts?

var d4;

(function() {
  'use strict';

  var root = this;
  var breaker = {};

  // Create a safe reference to the d4 object.
  d4 = function(obj) {
    if (obj instanceof d4) {
      return obj;
    }
    if (!(this instanceof d4)) {
      return new d4(obj);
    }
    this.d4Wrapped = obj;
  };
...

Looks reasonable to me. I'd suggest making this change as a PR after you ensure all tests pass (and adding tests as you feel necessary). I'd be happy to merge it down then.
