zz structure : Cosmology for a Different Computer Universe: Nelson: JoDI

Cosmology for a Different Computer Universe: Nelson: JoDI - Working with spreadsheets a lot lately - my latest concept was that
spreadsheet cells ought to be able to contain spread sheets.
For some reason, in an excel spread sheet, you can insert a document by reference, but
not another spread sheet. If this were true, your spread sheet could
become a zzstructure manager (?).
