This module implements the Levenshtein edit distance in a \s-1XS\s0 way.
.PP
The Levenshtein edit distance is a measure of the degree of proximity between two strings.
This distance is the number of substitutions, deletions or insertions (\*(L"edits\*(R") 
needed to transform one string into the other one (and vice versa).
When two strings have distance 0, they are the same.
A good point to start is: <http://www.merriampark.com/ld.htm>
