My Notes
--------
7 August 2023

In this workbook I explore Config A, the simplest approach, from my notebook.
In fact, it's actually simpler than what I describe in the notebook.

I use DefaultContent instead of behavior
  - so I can have same shared behavior for multiple different instances of PftbConfigA

TODO
- for the Cell Model
 - also include the IH binary strings
 - also include the two dictionaries
  - these provide names

TODO
- DONE include an example of a complete JSON structure that includes all of this
 - put it inside of a Xholon Attribute_String

### References
--------------
(1) see my notebook for 7 August 2023
    Instead of "Path Following Tree Builder", I call these "Path Oriented Tree Builder"
    I describe three configurations  Config A|B|C
