				.init()
				This function essentially makes it so that setting menu rollovers can be done in a 
				global file while the parameters are the only local pieces set in each file. For this 
				object to function properly you must pass it four parameters with the call
				init([a],[b],[c],[d]) where [a] represent the extension for the over state of an image.
				(eg. dormant state = [imgname]_o.jpg where '_o' is the over state. The same is true 
				for [b] which expects a dormant state (eg. '_d') string.
				
				The same holds for the third paramter [c] which expects the actual image type (eg. 
				jpg, gif, png, etc.,...) without the '.' which is added in the function call 
				automatically.
				
				The last paramter [d] expects an array of the image names (strings) you want to make 
				swappable on the particular page from which bpi_init is being called. The images listed 
				in this array must have their id and name tags set in the html code for the function 
				to work.
				
				.resize()
				Calls a window resize function calculation based on the homepage design.
				
	Uses:		sa_menu_image_swap.js, sa_window_resize.js
	Required:	This object must be created in the master site script or page head script before 
				being initiallized in the body "onload" attribute.
				
	Settings:	None
