Popular Words Counter

Counts popular words in passed text

Limitations

• Uses naive text tokenizer - thinks that everything except letters, ' and ` symbols is words delimiter
• Does not support languages without words delimiters (e.g. Chinese, Japanese, Khmer, etc.)
• Also splits compounded words to separate tokens (i.e. "user-friendly" => ["user", "friendly"]
• When there are more than $topQuantity words with same frequency, alphabetical ordering will be applied
