Confusion Matrix in CNNExample does not contain any information

@Nikoschenk You have to run the .eval method before you look at the confusion matrix. Simply move your print lines to below the eval.eval like so:

` int[] predictedLabels = model.predict(irisTest.getFeatureMatrix());

    // CONFUSION MATRIX DOES CONTAIN ONLY ZERO VALUES !!!
    //System.out.println(eval.getConfusionMatrix().toCSV());
    // SAME HERE !
    //System.out.println(eval.getConfusionMatrix());


    eval.eval(irisTest.getLabels(), output);
    log.info(eval.stats());
    // CONFUSION MATRIX DOES CONTAIN ONLY ZERO VALUES !!!
    System.out.println(eval.getConfusionMatrix().toCSV());
    // SAME HERE !
    System.out.println(eval.getConfusionMatrix());

    log.info("\n");
    log.info("****************Example finished********************");`
