ENH: adjustments for Function1/PatchFunction1

- additional debug information

- improve support for dictionary specification of constant, polynomial
  and table entries. These previously only worked properly for
  primitiveEntry, which causes confusion.

- extend table Function1 to include TableFile functionality.
  Simplifies switching and modifying content.
