/*
Finally for NN6's methods to parse in html into a document fragment we 
need to make sure that we create the range in the correct frame

  var html = '<DIV STYLE="position: absolute;';
  html += ' left: 100px; top: 200px;';
  html += ' width: 200px; height: 200px;';
  html += ' background-color: lime;';
  html += '">';
  html += '<H1>Kibology for all<\/H1>';
  html += '<\/DIV>';
so after creating the html we call
  var range = parent.frameName.document.createRange();
then position the range as needed in the other frame
  range.setStartAfter(parent.frameName.document.body.lastChild);
create the document fragment as before
  var docFrag = range.createContextualFragment(html);
which can be added with DOM methods to the document (body) of the frame
  parent.frameName.document.body.appendChild(docFrag);
