Hi... The new version has a NetworkAPIDemo.java file in the examples package. Also the github repo has a wiki link which has a NAPI Quick Start Guide - which links you to a growing set of tutorial pages (work in progress). Then there's the NetworkTest.java which can also be gleaned for info. But the Quick Start wiki is best - it is amazingly simple to get started. If you write to the nupic hacker's mailing list, I will be glad to help you - or if you go to http://gitter.im/numenta/public - you can get live help...
