Why the RFTrainer is very slow? #252

It was very slow that using the RFTrainer to train 600000 samples with 4 features in shark 3.0.0, and it didn't finish after waiting for dozens of minutes. When I use Random Forest to train the same data in sklearn, it took only a few seconds. So what is the reason? Did I lose other libraries when I compiled it?

Try the 4.0 version, it is a complete rewrite.

Feel free to close this, if 4.0 fixes your issue.
