Explode explodes a crowd image into 256x256 squares for learningtoCount. Added call to explode in getRegressor. changed algorithm used in doDictionary. Added validation set in Kfold. Added apply_msmrf which applies the mrf to a result structure. global_error_plot now also plots mrf estimations if available. Fixed mrf counting (forgot the scale change)
