爱华网zTree插件的基本功能全部实现：
前段时间工作需要对zThree进行了研究：对照zTree的API进行使用
动态链接数据库：实现增删改查，和单个多个节点拖拽功能，使用Ajax和数据库动态更新。
首次加载
$.fn.zTree.init($("#treeDemo2"),setting2, zNodes2);
$.fn.zTree.init($("#treeDemo"),setting, zNodes);
如果是现实多颗树需要多个setting和zNodes使用
addDiyDom 用于在节点上固定显示用户自定义控件
addHoverDom用于当鼠标移动到节点上时，显示用户自定义控件，显示隐藏状态同 zTree 内部的编辑、删除按钮
removeHoverDom用于当鼠标移出节点时，隐藏用户自定义控件，显示隐藏状态同 zTree内部的编辑、删除按钮
