+function confMat = evaluate(classifier, imageSet)
+// This function is used to evaluate an image classifier.
+//
+// Calling Sequence
+// confMat = evaluate(classifier, imgSet)
+//
+// Parameters
+// confMat: Confusion matrix as a result of the evaluation
+// classifier: Image category classifer
+// imgSet: An imageSet struct to be evaluated
+//
+// Description
+// This function evaluates an image category classifier on an input image set.
+//
+// Examples
+// imgSet = imageSet(directory,'recursive');
+// [trainingSet testSet] = partition(imgSet,[0.8]);
+// bag = bagOfFeatures(trainingSet);
+// categoryClassifier = trainImageCategoryClassifier(trainingSet, bag);
+// confMatrix = evaluate(categoryClassifer, testSet);
