Investigate F-Score based Feature Ranking #34

@kdiverson I've been reading the paper titled "Combining SVMs with Various Feature Selection Strategies", which was suggested by Rafi, it lists a combined system of SVM+F-Score+RandomForest which looks quite interesting.

I've already implemented the F-Scoring system, but I'd need to integrate it with RandomForest to see if it can provide any performance improvements.

The F-Score based system is practically a very refined version of the standard deviation (or variance) based feature discarding system that we already have.

Cool, good find. Perhaps this will be a version 2 option
