/**********************************************************************
 * Tabbed Box script
 *
 * Usage:
 *
 * create a tabbed box as follows:
 *
 * var ts = new TabbedBox(parent, tabs, initial);
 *
 * parent	= a page element that will be the container for the tabbed box
 * tabs		= a JS array where each item is an object with the properties below
 * initial	= id of the initial tab to have selected
 *
 * Each tab object has the following properties:
 *
 * caption		: text to display on the tab
 * id			: an identifer for the tab
 * docId		: (optional) The identifier within the document of an element to use
 *                for the content of the tab.  When the tab is selected
 *                this element will be removed from its current location
 *                and added to the tabbed box content area.
 * fncRender	: (optional) A function that will be called to render the contents
 *                of the tab.  The container div will be passed as an argument.
 * fncInit		: (optional) A function that will be called after the tab content
 *                has been rendered for the first time.
 * fncClick		: (optional) A function that will be called whenever the tab is clicked
 *
 * For example, the follow code will create a tabbed box with the two tabs labelled
 * "Shares" and "Managed funds".  Each tab specifies the id of a document element
 * to use as the tab content and a function to call to initialize each tab.  The
 * tabbed box will be a child of the "container" element and the first tab shown
 * will be the "Shares" tab.
 *
 * var tabs =
 * [
 *		{
 *			caption	: "Shares",
 *			id		: "s",
 *			docId	: "SharesTab",
 *			fncInit	: function() { qs_shares_loadInfoRequest(); }
 *		},
 *		{
 *			caption	: "Managed funds",
 *			id		: "mf",
 *			docId	: "ManagedTab",
 *			fncInit	: function() { qs_managed_loadInfoRequest(); }
 *		}
 * ];
 *
 * var tb = new TabbedBox(document.getElementById("container"), tabs, "s");
