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).

Got better generalization via "analogy method" with additional wrinkle: after both neurons in hiddenLayer2 were trained on ALL EXAMPLES, which very significantly improved the 2 neurons hyperplane angles, THEN these 2 neurons were context controlled and "fed" to the output layer fro supervised training.  Which worked very well.
