============= CHANGELOG ==================
17 June 2005 [17:46] [Sarat Pediredla]
- Modified code to replace getAttribute().toLowerCase() with tmpString
because strangely IE 6.0 wont support it.
18 June 2005 [08:45] [Sarat Pediredla]
- Added functions to get X & Y position of elements.
- Modified style setters to use element.style.cssText
