Improve Tree Class doc

[maurever]

We need better documentation about our tree objects.

Issues and ideas:

• We generate the Python doc about trees here: https://docs.h2o.ai/h2o/latest-stable/h2o-py/docs/tree.html (very short description at the beginning) and for R here https://docs.h2o.ai/h2o/latest-stable/h2o-r/docs/reference/H2OTree-class.html (no description). Some attributes have no description and example, for example, tree_decision_path and decision_paths.

• Here is a ridiculous example about accessing the trees from MOJO: https://docs.h2o.ai/h2o/latest-stable/h2o-docs/mojo-capabilities.html#accessing-model-trees

• Here is a nice blog post about tree traversing (https://dzone.com/articles/inspecting-decision-trees-in-h2o); we should have something similar in our documentation (real Java, Python, and R examples).

I suggest creating a separate page about trees in H2O where all available tree features are demonstrated.

If something like this is currently done, please share the link here. I did not find something like that.

Any other ideas or improvements are welcome.
