A library to calculate a metric indicating the string distance between two strings
It also exposes two utility functions for finding general Longest Common Subsequence.
StringDistance was extracted from the port of mailcheck.js to Elm which is https://github.com/rluiten/mailcheck.
The mailcheck library refers to http://siderite.blogspot.com.au/2007/04/super-fast-and-accurate-string-distance.html as source of string distance algorithm.
