Model Changes w Macros

[seandenigris]

Two use cases jump out:

• Field dependencies e.g. for web forms. For example, I have an online compounding interest calculator. If one field is changed, another should autoupdate. For more info, see Field Dependencies #152.
• Checked mementos. Right now there are dumb dictionaries. The problem is when the model is more complex than "one change affects one field".

Use case: I have a "Federal Register" work representing the series. Now, I have a particular issue "Vol. 87, No. 18/Thursday, January 27, 2022" that I want to add as a child. Currently, the to-many relations just copy the collection and add a new item, but in this case, the parent implements #addChild: because there is mutual setup to be done between the parent and the child. I don't see how this can be handled with the current API. There is the initialization block, but this setup should only be done if the child is actually added, not on child creation.
