digitalmars.D - Levenshtein Distance algorithm

Hello,

Some time ago, Walter mentioned that it might be possible to contribute code to
Phobos.  He specified three possible ways of doing so, the first option was
public domain.  I have written a simple implementation of the Levenshtein
Distance algorithm for two strings which I am contributing to the public domain
for possible use by Digital Mars or anyone else in case anyone is interested. 
It is attached to this message, along with a few simple tests.  The
implementation should be sound; I also tested it against a file of over 100,000
words and their pronunciations.  The result was in every case identical to the
PHP implementation of Levenshtein function (see http://us2.php.net/levenshtein).
