Installation
-------------
In BaseX (command line client): REPO INSTALL StringSimilarity.jar

Usage
-------------
In a query, import the module and call a function like so:

import module namespace s = "org.basex.modules.StringSimilarity";

s:Levenshtein("house", "home")

Functions
-------------
Generic:
similarity(String metric, String s1, String s2): Return the normalized similarity value between s1 and s2, using metric.
similarity_raw(String metric, String s1, String s2): Return the unnormalized similarity value between s1 and s2, using metric.

Metric specific:
<metric_name>(String s1, String s2): Return the normalized similarity value between s1 and s2, using metric_name.
<metric_name>_raw(String s1, String s2): Return the unnormalized similarity value between s1 and s2, using metric_name.
