This is a sample to use the new %JSON.Adaptor class available in IRIS
to produce a snapshot of your object.
The sample consists of 2 classes that are variations of what was
known in Caché/SAMPLES as Sample.Person.
Be aware that the possibilities are limited by %JSON.Adapter
and how you make use of it.
Once in place you create some test data by Populate().
You select an object and take a snapshot.
You apply changes to your object take another snapshot.
And see the difference.
