一个jquery tree插件

1.4 --- * Added changelog (this file) * Fixed tree control to search only for anchors, allowing images or other elements inside the controls, while keeping the control usable with the keyboard * Restructured folder layout: root contains plugin resources, lib contains script dependencies, demo contains demos and related files * Added prerendered option: If set to true, assumes all hitarea divs and classes already rendered, speeding up initialization for big trees, but more obtrusive * Added jquery.treeview.async.js for ajax-lazy-loading trees, see async.html demo * Exposed $.fn.treeview.classes for custom classes if necessary * Show treecontrol only when JavaScript is enabled * Completely reworked themeing via CSS sprites, resulting in only two files per theme * updated dotted, black, gray and red theme * added famfamfam theme (no lines) * Improved cookie persistence to allow multiple persisted trees per page via cookieId option * Improved location persistence by making it case-insensitive * Improved swapClass and replaceClass plugin implementations * Added folder-closed.gif to filetree example 1.3 --- * Fixes for all outstanding bugs * Added persistence features * location based: click on a link in the treeview and reopen that link after the page loaded * cookie based: save the state of the tree in a cookie on each click and load that on reload * smoothed animations, fixing flickering in both IE and Opera * Tested in Firefox 2, IE 6 & 7, Opera 9, Safari 3 * Moved documentation to jQuery wiki * Requires jQuery 1.2+
