[BioRuby] New 'bio/lib' directory suggestion, for comments

[Trevor Wennblom]

I'm looking for comments as to if we should create a 
"bioruby/lib/bio/lib" directory.  The purpose of this directory would be:
* To contain code that some BioRuby modules depend on
* that is unlikely to be on a users system
* and is relatively small in size

At the moment Permutation[1] is what makes ask the question, but I can 
see other math packages facing the same question in the future.

Thanks,
Trevor
