% Calls Classification Random Forest
% A wrapper matlab file that calls the mex file
% This does prediction given the data and the model file
% Options depicted in predict function in http://cran.r-project.org/web/packages/randomForest/randomForest.pdf
%**************************************************************
%function [Y_hat votes] = classRF_predict(Xmodel extra_options)
% requires 2 arguments
% X: data matrix
% model: generated via classRF_train function
% extra_options.predict_all = predict_all if set will send all the prediction.
%
%
% Returns
% Y_hat - prediction for the data
% votes - unnormalized weights for the model
% prediction_per_tree - per tree prediction. the returned object .
% If predict.all=TRUE then the individual component of the returned object is a character
% matrix where each column contains the predicted class by a tree in the forest.
