Part 1: Adding Supplements to Exhibit Editing

This builds out a rough fieldset element for Supplements.

This is a fall-back position before I try to create a Helper Class inside the Element.

The tasks for this one are pretty complex and I started adding functions to break things up. Then the functions started needing to move variables in and out of themselves and…

Going to a Class might help this. Besides, this Element needs to make some Form HTML and that requires the Form Helper (which is not available in an Element).

So this Class is going to extend FormHelper… I hope.
Nearly done adding Supplements to the form

Class-ifying the Element wasn't as easy as it seemed. Instead, I worked within the existing $parameters array, passing the whole thing into the functions.

I'm removing he add/delete Supplement javascript for now. To get new Supplement data points, you'd have to add them to the Category default list. Then they would appear.

Next, saving the data.
Finalize Exhibit Edit

This gets the Exhibit Edit process to a workable stage.

It may need other features like
delete, clone or routing to other edit screens. Later though.
