Several bug fixes.
Dev release of Hypergraph for Drupal 6
Port to Drupal 6, improved on many fronts, seemingly stable.
Devel and other modules sometimes added extra stuff into the generated XML and the Java applet was not able to render the graph. See http://drupal.org/node/237239
* Added database caching.
* Added file system caching.
* Totally new routine for menu network generation.
* Fixed a nasty bug reported at http://drupal.org/node/179003
Fixed a problem with the .info file (hypergraph did not show in the list of modules).
Added depth-dependent label colouring, fixed some minor bugs.
Initial release. Hypergraph module takes the menu tree of user's choice and turns it into its visual equivalent.
Initial, very premature foetus.
