		 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")
