How to contribute code?

[sgyaqing]

Hi,

I wrote an external program to call to H2ORandomForestEstimator.train() in Python. My program should show the progress when training but there is no method to get the progress.

I saw the source code and thought about to add a "callback" parameter to train(). How can I contribute code? There is no "issue" column for this project in github. Directly pull request?
