Barcode::DataMatrix::Reed3pm

Overview

This is just a renamed version of Algorithm::DataMatrix::Reed by Mons Anderson from http://code.google.com/p/perl-ex/

For a rough explanation of the structure of this code, see <https://en.wikiversity.org/wiki/Reed%E2%80%93Solomon_codes_for_coders#Reed.E2.80.93Solomon_codes>. Note that the link is not the basis of the implementation (this is unknown), however it helps explain how Reed-Solomon encoding is implemented and hence how the code below works.
