[Chameleon] My tree legend solution

[Gambin Dejan]

Hi,

I have realised a legend tree solution that suits my needs. Now, if
anyone is interested in this, I will be happy to share it. 

Besides, if Paul or some other experienced Chameleon developer is
willing, I would rather first explain what have I done, to hear their
comments and potential recommendations for improving/changing something
so I can possibly improve/change it and then post it to some public
place (Wiki or something)

regards, dejan
