Fixed bug related to the distribution getting only the first value (negative class) when combined with other distributions. AUPR is now ~40 and ROC ~80. Implemented Balanced Random Forests and now tweaking parameters.
Added two new impurity measures: weighted_gini and max_p. also added the ability to prune the forest based on oob error. though the oob error is inaccurate for certain combinations of classifier - balanced/weighted.
