See www/map.php or www/jaollisuus.html for examples.

Examples use John Beachy's Abstract Algebra On Line -book 
(http://www.math.niu.edu/~beachy/aaol/) and a concept map 
by an unknown math student.

NEW FEATURES
------------
  Browsing with keyboard.
  (arrows browse, enter activates node link, ESC closes hint)

  php-based applet framework (see www/map.php).

  Edges can have labels.

  localitySB can be set to graph file.
  ackSelectColor can be customized in graph file.
  SBs and offsets are functional even if InitialNode is applied.


NOTE
----
 TGLinkBrowser.jar and nanoxml-2.1.1.jar are moved to subdirectory www.

 file map.php is hard-coded to link handling method. If such
 name is found on node link, it is opened on same frame as
 original applet.

 this package is tested only as a browser applet.


ISSUES
------
 Applet does not always get keyboard focus on Mozilla on Linux.
 Workaround:  focus to another window and then back to applet.
