Lua - IUP - 控件 tree
    iup.TreeAddNodes(tree, ..)(等设置内容的操作) 需在 iup.Show() 后。
( iup.dialog{tree; ..} 在 iup.Show() 前 )
(否则,控件 tree 内容为空)
((至少)控件 list 非如此)
(对 iupx.show_dialog(..) 仍无效,即,控件 tree 内容为空 )
        示例中非按此实现
    文档
      the initialization must be performed after the tree is mapped.
        IUP - Protable User Interface (iup-3.16_Docs.chm) IupTree Notes Hierarchy  ..
        map - iup.Show()
      Ignored if set before map
        IUP - Protable User Interface (iup-3.16_Docs.chm) IupTree Attributes ADDLEAFid / ADDBRANCHid / ..

路径
  可以用'/',或用'\'(转义)做分隔符。

IUP 常量
  IUP_NOERROR — iup.NOERROR (Lua绑定)
