WordPress Custom Walker Class to remove unnecessary classes and ID's from menu items

/*-----------------------------------------------------------
    Custom Walker Function that only shows an active class 
	and unique ID for each menu item, stripping out all the
	unnecessary classes and ID's. Nice!
