Now Going to Ruby 2.1.3

Moved classes to files with more appropriate filenames.  Also Just moved alot files into "unmaintained" category.

Continued to simplify "train" method by creating helper/builder methods to simplify specification of the 'learner'...

Made 2 more bins:  (1) continued series with learning without context for hidden layer 2. (2) simple 2-bit A to D converter learner.  More improvements and simplifications.

mades some small changes.  Need to debug Proj4SelfOrg...

Got software debugged I think.  But now am learning from simulations...

More work.  See Evernote notes for this date (approx).

Learning alot! particularly about "clustering" and information content of lower layers and its impact of supervised learning in the upper layer(s).
