//Site Wide Script File
//This file contains scripting for the entire site
		//Popup Script that defines window size ect for popups (Used in photo album link and others)
		
		//Google API For Calling the Google via Search Box (Used in the google search box)
			//**also requires the script ref to google in the head**
			
		//Site Apearence Code (Adds in extra HTML to properly format the design)
			//**Uses jquery so keep that script #ref!
		//Site Drop Down Menu Code (for Fast Links)
		
		//A Stylesheet switcher for dynamically changing the apearence (used for accessability options and themes)
			//**This must be at the end of the head code!!**
