Ratcliff-Obershelp String Matching, otherwise known as Gestalt Pattern Matching. This crate contains a single function, which computes a similarity score between two strings, based on recursively looking at longest common substrings. The algorithm is described in this wikipedia page: https://en.wikipedia.org/wiki/Gestalt_Pattern_Matching
As of version 0.2.0 this crate supports unicode strings. Strings are compared using their extended graphemes, as provided by the unicode_segmentation crate.
Produces a string similarity score between 0 and 1.
