/**
 * <p>Provides algorithms for string similarity.</p>
 *
 * <p>The algorithms that implement the EditDistance interface follow the same
 * simple principle: the more similar (closer) strings are, lower is the distance.
 * For example, the words house and hose are closer than house and trousers.</p>
 *
 * <p>The following algorithms are available at the moment:</p>
 *
 * <ul>
 * <li>{@link org.apache.commons.text.similarity.CosineDistance Cosine Distance}</li>
 * <li>{@link org.apache.commons.text.similarity.CosineSimilarity Cosine Similarity}</li>
 * <li>{@link org.apache.commons.text.similarity.FuzzyScore Fuzzy Score}</li>
 * <li>{@link org.apache.commons.text.similarity.HammingDistance Hamming Distance}</li>
 * <li>{@link org.apache.commons.text.similarity.JaroWrinklerSimilarity Jaro-Wrinkler Distance}</li>
 * <li>{@link org.apache.commons.text.similarity.LevenshteinDistance Levenshtein Distance}</li>
 * </ul>
 *
 * <p>The {@link org.apache.commons.text.similarity.CosineDistance Cosine Distance}
 * utilises a {@link org.apache.commons.text.similarity.RegexTokenizer regular expression tokenizer (\w+)}.
 * And the {@link org.apache.commons.text.similarity.LevenshteinDistance Levenshtein Distance}'s
 * behaviour can be changed to take into consideration a maximum throughput.</p>
