TreeElement - link labels.

[krs-world]

The TreeElement example seems to generate link labels without specifying any. The default should be the null string. Not sure how it is getting a default label (1 in the web tutorial example and in my current version, 1s and 2s for the links). Need to be looked at.

And here is the JSON:
