A fuzzy string set data structure for approximate string matching.

In a nutshell:

1. Add data to the set (see `add`, `add_`, `addMany`, and `addMany_`)

2. Query the set (see `find`, `findMin`, `findOne`, `findOneMin`, `closestMatchMin`, and `closestMatch`)

Refer to the [Haddock docs](http://hackage.haskell.org/package/fuzzyset) for details.

## Example

```haskell

{-# LANGUAGE OverloadedStrings #-}

module Main where                                                               ```

import Control.Monad.Trans.Class (lift)

import Data.Text (Text)

import Data.FuzzySet (FuzzySearchT, add_, closestMatch, runDefaultFuzzySearchT)

findMovie :: Text -> FuzzySearchT IO (Maybe Text)

findMovie = closestMatch

prog :: FuzzySearchT IO ()

prog = do

  add_ "Jurassic Park"

  add_ "Terminator"

  add_ "The Matrix"

  result <- findMovie "The Percolator"

  lift (print result)

main :: IO ()

main = runDefaultFuzzySearchT prog

```
