CHANGES SINCE VERSION 0.2.2

Primarily code fixes for SGI platform.  Added a new configure option
to make it easy to compile Fl_ToggleTree if fltk is in a non-default
directory (read INSTALL).

CHANGES SINCE VERSION 0.2.1

This has a few more fixes and includes code to draw lines between
toggle nodes (like the win32 or Gtk collapsible list widgets).  Thanks 
to Petr Vilim for contributing this.  This feature can be turned on
and off.  More color configurability was added and the tree demo was
updated to show off these features.

CHANGES SINCE VERSION 0.2.0

This is mostly a bug fix release that addresses patches submitted by
Petr Vilim, Alexandre Liduena and bug reports submitted by other
users (Thanks!).  It also adds methods for changing colors.

CHANGES SINCE VERSION 0.1.0

Most of these changes have been made by James, some by my.
I appreciate it a lot that James started participating in
the development of Fl_ToggleTree, and I never had expected
the huge amount fo contributions he made. 

Version 0.2 is not, I repeat not, very backwards compatible
with Version 0.1, but I think it is worth rewriting your
code for. I did :-) 

Main changes include:

  - a lot more FLTK coding style compliant 
  - beter way to keep track of open/closed items
  - easier tree maintenance (moved from seperate
    class into Fl_ToggleTree
  - going through a selection with an index
  - sorting
  - multi-column (like Fl_Browser)
  - editing of label
