Title: mFeature Parameter

This parameter is an integer value (or rounded to an int) that represents the number of features to consider at each node of a tree. This reduce the computation time by not testing every feature at every node in the trees. This may require additional tree to be trained to find the optimal number of trees, but the time lost in training more trees is less than the time saved from limiting the features at each node.
