anchor.diff:          var arg1 = dom.byId("num1");
           var arg2 = dom.byId("num2");
           var result1 = dom.byId("result1");
  -        var result2 = dom.byId("result2");
   
           // Simple object with some methods
           var theAccumulator = {
  
positive.code:     First Argument: <span id="num1">1</span>
      </div>
      <div>
      Second Argument:  <span id="num2">2</span>
      </div>
  </div>
  <div>
      <div>
      First, we illustrate incorrect usage:
  
negative.code:     First attempt: <span id="result1"></span>
      </div>
  </div>
  <hr />
  <div>
      <div>
      Now, we illustrate correct usage:
      </div>
      <div>
      Second attempt: <span id="result2"></span>
      </div>
  </div>
  <hr />
  <div>
      <div>
          Let's try another example.  Clicking the button will show nothing.  But opening the console log will show that
          "this.result3" is undefined.
      </div>
      <div>
          <button id="attempt3">Fire Event</button>
          Third attempt: <span id="result3"></span>
      </div>
  </div>
  <hr />
  <div>
      <div>
          And now we'll do the same exmaple but we'll bind a different context to the execution with hitch.
      </div>
      <div>
          <button id="attempt4">Fire Event</button>
          Forth attempt: <span id="result4"></span>
      </div>
  </div>
