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...
