lazyTree sample:
This sample shows

• Adding document and folder nodes using addDoc() and addFolder()in the onload-event.
  (Note that also documents may have children.)
• Hiding the main root using the bRootVisible flag.
• Using the onSelect callback to give feedback when a node is selected.
• Using the bAutoCollapse flag to make sure only one path is expanded at a time.
• Using addLazyFolder() and a onLazyRead callback to implement a lazy folder sample.
• Using the extended node configuration to set custom icons and tooltips.
  Also, any additional data can be passed and accessed in the callbacks using tn.data.attribute.

(Remove the div-tag with id idLogPanel to suppress debug output.)
