        /* Options (in any order): 
 
        start (number|string) 
        Index number of default tab. ex: $(...).idTabs(0) 
        String of id of default tab. ex: $(...).idTabs("tab1") 
        default: class "selected" or index 0 
        Passing null will force it to not select a default tab 
 
        change (boolean) 
        True - Url will change. ex: $(...).idTabs(true) 
        False - Url will not change. ex: $(...).idTabs(false) 
        default: false 
 
        click (function) 
        Function will be called when a tab is clicked. ex: $(...).idTabs(foo) 
        If the function returns true, idTabs will show/hide content (as usual). 
        If the function returns false, idTabs will not take any action. 
        The function is passed four variables: 
        The id of the element to be shown 
        an array of all id's that can be shown 
        the element containing the tabs 
        and the current settings 
 
        selected (string) 
        Class to use for selected. ex: $(...).idTabs(".current") 
        default: ".selected" 
 
        event (string) 
        Event to trigger idTabs on. ex: $(...).idTabs("!mouseover") 
        default: "!click" 
        To bind multiple event, call idTabs multiple times 
        ex: $(...).idTabs("!click").idTabs("!focus")
