Confusion in README

[Berkmann18]

I've noticed that the cross-validation example uses macroAverage:

var macroAverage = new limdu.utils.PrecisionRecall();

limdu.utils.partitions.partitions(dataset, numOfFolds, function(trainSet, testSet) {
	console.log("Training on "+trainSet.length+" samples, testing on "+testSet.length+" samples");
	var classifier = new IntentClassifier();
	classifier.trainBatch(trainSet);
	limdu.utils.test(classifier, testSet, /* verbosity = */0,
		microAverage, macroAverage);
});

macroAverage.calculateMacroAverageStats(numOfFolds);
console.log("\n\nMACRO AVERAGE:"); console.dir(macroAverage.fullStats());

But utils.testAndTrain's test function uses macroSum which is confusing.
Is it meant to be macroSum in the README or is the function not using the right term?

Also, not related to this but would it be a good idea to add (an optional) randomization to the partitions (e.g.: like how train-test-split does it)?
