This test does a few things:
  - It has a couple of:
  
  
- It dumps (check the JS console) the images, links and anchors using
      the document.images, document.links and document.anchors arrays.
  
- Then it removes one of the images.
  
- Dumps the images array again. This is to prove that the images array
      is live.
  
- Adds back the image.
  
- And the dumps the images array again. The image arrays order should
      now be different.
  
- It gets a list of LIs (using getElementsByTagName()) and prints
      out all their tagNames. There should be 10.
