//Drop Down/ Overlapping Content: http://www.dynamicdrive.com
//**Updated: Dec 19th, 07': Added ability to dynamically populate a Drop Down content using an external file (Ajax feature)
//**Updated: Feb 29th, 08':
				//1) Added ability to reveal drop down content via "click" of anchor link (instead of default "mouseover")
				//2) Added ability to disable drop down content from auto hiding when mouse rolls out of it
				//3) Added hidediv(id) public function to directly hide drop down div dynamically

//**Updated: Sept 11th, 08': Fixed bug whereby drop down content isn't revealed onClick of anchor in Safari/ Google Chrome
