areas and input controls

   - Need to be able to ensure text content wrapping in non-visible shadow
DOM
   - Need to be able to acquire grammar and spell checking errors in
content editable areas (these would be ranges)
   - Can we achieve a common API for these across browsers?
- Need to develop examples

Reference Material APIs:
- Browser API Comparisons for Caret Tracking and Content Selection:
http://www.quirksmode.org/dom/w3c_range.html
- Getting the selection object:
https://developer.mozilla.org/en/DOM/window.getSelection
- sel = window.getSelection() //sel is a Selection object
- rangex = sel(0);
- rangex.collapsed(); //If it is collapsed it is a caret
- reangex.collapse();
