Closestmatch is a simple and fast Go library for fuzzy matching an
 input string to a list of target strings. closestmatch is useful for
 handling input from a user where the input (which could be misspelled or
 out of order) needs to match a key in a database. closestmatch uses a
 bag-of-words approach (https://en.wikipedia.org/wiki/Bag-of-words_model)
 to precompute character n-grams to represent each possible target
 string. The closest matches have highest overlap between the sets of
 n-grams. The precomputation scales well and is much faster and more
 accurate than Levenshtein for long strings.
