WARNING! Do not assume the Excel file in this repo matches the VBA in
the repo. The decision was made to use Teams for managing changes to the
Excel tamplate because Git is ill-suited for binary files. The Excel
file will be updated from time to time, but only when something major
happens with the application as a whole.
1. Use the sheets' codenames to refer to them in code. This prevents
breakage if the user changes the sheet name while working with the
workbook.
2. Give the pivot tables proper, if not descriptive, names.
3. Simplify the code that detects a double-click in the pivot table.
4. Remove Windows_API as it was not being used.
5. Pare down TheBigOne to just the essential functions in Utils.
6. Refer to the data sources for the userforms' listboxes by using the
worksheet.ListObjects collection.
