[BioRuby] CodeML wrapper for BioRuby

[Michael Barton]

Hi,

CodeML is a common tool for estimating evolutionary rate of protein encoding
sequences, and is part of the PAML package. I've created a codeml wrapper
and two parsers. Unit tests are also included. The code is in a Github fork
in BioRuby. The fork is located here

http://github.com/michaelbarton/bioruby/tree/master

I like to suggested that it for inclusion in the main BioRuby branch.

Thanks

Mike
