[Cuis] Cuis-Smalltalk-Learning - ReBoot

[Ken.Dickey]

Greetings,

I have made another attempt at
  https://github.com/Cuis-Smalltalk-Learning

The README.md file for Learning-Cuis now refers to both the Quick UI Tour and the start of a Package Reference.

Ideally, someone will write a Package Reference Browser, but in the short term I encourage you all to add package descriptions to 'PackageRef.md', which I hope to be machine parsable at some point.  I volunteer to add the Cuis Base Packages as soon as I get to it.

Thanks in advance for feedback and suggestions!
