AbstractClassifier中的enableProbability方法似乎有BUG

[orangeclk]

Describe the bug
用户调用enableProbability(boolean enable)后，不管传入的值是true还是false，都不会影响到configProbabilityEnabled的值，从而导致 if (configProbabilityEnabled) MathUtility.normalizeExp(predictionScores); 永远执行。

建议将

    @Override
    public IClassifier enableProbability(boolean enable)
    {
        return this;
    }

修改为

    @Override
    public IClassifier enableProbability(boolean enable)
    {
        configProbabilityEnabled = enable;
        return this;
    }

Code to reproduce the issue
Provide a reproducible test case that is the bare minimum necessary to generate the problem.

    public Map<String, Double> test() throws IOException {
        IClassifier iClassifier = new NaiveBayesClassifier(trainOrLoadModel()).enableProbability(false);;
        return iClassifier.predict("test java demo"); 
}

Describe the current behavior
enableProbability方法失效。

Expected behavior
enableProbability方法生效。
