OpenDCL Tree-Tabs Demo

[Slavko Ivanovic]

Here's a little something to share.
Using Tree as Tab navigation.
Good:
- Clear & Categorized display of tabs & navigation.
- Use many tabs in one tab strip.
- Don't have to worry about TabOrder, (display last Tab as 1st in tree)
- Don't have to use Tab Events (only 2),
  instead combine any of rich Tree Events when switching.
- Don't have to use TabCaptions, only work with TabIndex s.
...

Put all files (2) in ACAD support file path and appload "lspTreeTabsDemo.LSP".
Enjoy
