%description
This module implements the Brew edit distance that is very close to the
dynamic programming technique used for the Wagner-Fischer (and so for the
Levenshtein) edit distance. Please look at the module references below. For
more information about the Brew edit distance see:
<http://ling.ohio-state.edu/~cbrew/795M/string-distance.html>

The difference here is that you have separated costs for the DELetion and
INSertion operations (but with the default to 1 for both, you obtain the
Levenshtein edit distance). But the most interesting feature is that you
can obtain the description of the edits needed to transform the first
string into the second one (not vice versa: here DELetions are separated
from INSertions). The difference from the original algorithm by Chris Brew
is that I have added the SUBST operation, making it different from MATCH
operation.

The symbols used here are:

 INITIAL that is the INITIAL operation (i.e. NO operation)
 MATCH	 that is the MATCH operation (0 is the default cost)
 SUBST	 that is the SUBSTitution operation (1 is the default cost)
 DEL	 that is the DELetion operation (1 is the default cost)
 INS	 that is the INSertion operation (1 is the default cost)

and you can change the default costs (see below).

You can make INS and DEL the same operation in a simple way:

 1) give both the same cost
 2) change the output string DEL to INS/DEL (o whatever)
 3) change the output string INS to INS/DEL (o whatever)
