Usage

let counter = new Counter();
let counter_another = new Counter();

let text = `I am firm, You are obstinate, He is a pig-headed fool. I am righteously indignant, you are annoyed, he is making a fuss over nothing. I have reconsidered the matter, you have changed your mind, he has gone back on his word.`
let tokenize = (txt) => txt.replace(/[,\.]+/g, '').split(' ')
let words = tokenize(text);

words.map(w => {
	counter.inc(w);
});

counter.incAll(words);
counter_another.incAll(['the', 'the', 'the', 'the']);

counter.keys();
counter.values();
counter.size();

counter.normalize();
counter.maxCount();
counter.argMax();
counter.elementwiseMax(counter_another);
counter.subtract(counter_another);
