-(Will this allow a more muddled design ?  Possibly, though starting out
-layered probably helped, but note previous comment:
-
-  Each layer can only reference things below it.  A seeming problem:
-  CookedLedger must be at the top so it can cache any of the others. Code
-  below it can not use its fast functions, and code above it should use
-  only its functions for good performance. Upper-level code loses the
-  benefit of many lower-level functions and has to reimplement them as
-  fast versions.)
