+// HISTORY
+// ------------------------------------------------------------------
+// December 9, 2003: Added script to the Javascript Toolbox
+// December 10, 2003: Added the preProcessTrees variable to allow user
+//      to turn off automatic conversion of UL's onLoad
+// March 1, 2004: Changed it so if a <li> has a class already attached
+//      to it, that class won't be erased when initialized. This allows
+//      you to set the state of the tree when painting the page simply
+//      by setting some <li>'s class name as being "liOpen" (see example)
+// March 29, 2005: Added cookie-managed state (AG).
