Title: Rf review

This is a preliminary review of the random forest code. I do not intend to push it in immediately. Any comments are welcome.

Since C4.5 share a lot of common code with random forest, we also changed c4.5 code. Please also review that part.

In this pull request, it includes all other pending pull request for decision tree.
